The Coastal Development Plan in Jiangsu Province had risen to national strategy in 2009. The significant ground work of coastal city in Jiangsu Province in the future is to acquaint the trajectories and driving forces of land use change in the past. In the present work, we utilized 5 periods of RS remote sensing images and GIS technology to analyze the land use structure and trajectories between 1980 and 2010. We identified the correlations between different environmental attributes and land use changes by canonical correspondence analysis. The results show that the major land use types were arable land (2029.02 km²), construction land(155.31 km²), grass land (60.41 km²) and water land (56.56 km²) in Dongtai city from 1980 to 2010. The variable quantity of land use accounted for 16.98% of the total area, and the arable land, grass land and construction land accounted most. The main land use change trajectory is arable land shift to construction land, followed by grass land shift to arable land. From the point of spatial distribution, the transfer from arable land to construction land mostly located in city and surrounding areas, the transfer from grass land to arable land mainly in the coastal zone areas. The two hot spot regions of land use changes in Dongtai city were city and coastal zone, which are relatively independent and lack of connections.CCA ordination reveals that the environmental attributes like distances to city, to town, to transportation and the shape of patches all had affected the transfer of land use significantly. However, the coastline as the major character of coastal city, with the development of tideland reclamation also had effect on changing the distribution of land use. Consequently, locations of infrastructure like the city and town, the transportation the shape of patches should be consider seriously. By means of change, the land use types in coastal zone can we promote social and economic transformation, further protect the coastal ecological environment, enhance comprehensive benefits of coastal development and lead land use to the sustainable development path.

In this study, we analyzed the changes of number and structure, and regional differences of construction land using various types of land use data of 16 cities in Anhui Province, and the canonical correlation analysis, principal component analysis and partial least square regression. Meanwhile we discussed the main influence factors and degree of urban construction land change. The results are shown as follows. The urban construction land of Anhui Province increased at an annual rate of 5.8% and the structure of urban construction land was reasonable. From the regional characteristics of the change of construction land of various cities in Anhui Province, the relative change rate of construction land use of the cities was distinct and the change in the eastern, central and southern regions was more apparent, and the change in the northern and western regions was relatively stable. The development of economy and the improvement of transport infrastructure and the improvement of people's living standards were the main driving factors in the urban construction land change in Anhui Province.

To investigate the resource dynamic of four rare and important economic fish i.e. Myxocyprinus asiaticus, Lateolabrax maculatus, Siniperca chuatsi, Channa argus, 2 or 3 samples per month were collected using a stow net along the Jingjiang section of the Yangtze River from 2002 to 2013Totally 379 samples were collected, with the catch yield of 112 587 and 681 080.2 g in weight. The samples were classified into 14 orders, 28 families and 77 genera 119 species. 476 fish belong to the four rare and important economic fish, accounting for 4.23‰ of the total catch yield. This included 224 Siniperca chuatsi the most; followed by 121 Lateolabrax macultus, 96 Channa argus, and 35 Myxocyprinus asiaticus. The 379 samples, Siniperca chuatsi, Channa argus, Lateolabrax macultus and Myxocyprinus asiaticus were caught 93, 83, 38 and 21 times, respectively. The corresponding sample rate were 24.54%, 21.90%, 10.03% and 5.54%. According to IRI, Myxocyprinus asiaticus was a rare species, Lateolabrax macultus the general species, while Siniperca chuatsi and Channa argus were the common species. However, annual IRI data indicated that the general species Myxocyprinus asiaticus and Channa argus had become the dominant species in the past three years. Both species tended to increase in population size. Further analyses suggest that the closed fishing season from April to June could protect 31.43% of Myxocyprinus asiaticus, 29.75% of Lateolabrax macultus, 18.3% of Siniperca chuatsi and 26.04% of Channa argus juvenile fish in Jingjiang section of the Yangtze River. If the closed fishing season extended till September, the figures would increase to 48.57%, 94.21%, 92.86%, 68.75%, respectively.

The South channel is one of the two major entrances of Yangtze River into the sea, and the necessary passage of the North deep-water navigation channel. In this paper, we collected the topographic maps and 12 sediment samples from 1984 and 2012, and compared the grain size of riverbed surficial sediment using the same method (sieve and pipette analysis) of the two years. The erosion and/or deposition of the two year was analyzed by using the ArcGIS software. The results showed that there was a major geomophological change in the South Channel during the past 28 years. Sand ridges in compound channels were dying out due to sediment erosion, whereas the main channel tended to be shallow to several meters due to siltation at the same time. Moreover, the median grain size of surficial sediment decreased from 81 μm to 24 μm, especially the sediment type on the original ridge changed from sand to sandy silt, even clayey silt. We determined that sand extraction mainly caused these changes in South channel because this activity led to the extinction of mid-ridges in the compound channels, weakened hydrodynamic environment, and amplified the area of the crossing-section. Siltation on both sides of the channel arose due to lessening in flow velocity. The sediment size became finer depending on combination of coarse sediment dredging, weakening current and slitting in the channel.

Land subsidence in the Shanghai City is mainly caused by the over exploitation of groundwater and loose strata compaction. Land subsidence has led to many secondary disasters. The monitoring data of F4 layerwise mark shows that land subsidence in the Shanghai City generally presented nonlinear variation. Especially since the 1980s, the data showed gradual vertical increases and constant spatial expansion. This change was slowed down until the 2001. In different periods, with the changes of groundwater exploitation and mining level, land subsidence exhibited different characteristics. The 20 years (1990-2009) fourth aquifer data showed the response of land subsidence to groundwater exploitation and reinjection: the land subsidence increased with intensified groundwater exploitation, and reduced with decreased groundwater exploitation, but the land subsidence relative to the groundwater exploitation lagged behind. The land subsidence amount reduced with the increase of the reinjection, and the effect of the groundwater recharge had a direct relationship with the recharged aquifer.

In this paper, a continuous heavy fog in January of 2014(i.e., 29-31 January) is studied at Wuhan-Yichang section in Shanghai and Chongqing highway (hereinafter referred to Han-Yi highway). Analysis showed as follows. (1)When this continuous heavy fog process happened, there was the inversion layer close to the ground. The ground field was in uniform pressure field, middle latitude flow field manifested by west air current, and these backgrounds provided favorable circulation conditions for the formation and development of the continuous heavy fog. (2)Monitoring data from the traffic weather stations at Han-Yi highway showed that the meteorological elements changed obviously when the highway was locked due to the heavy fog and the highway was unlocked. These analysis results are of good instruction significance for warning and forecast of heavy fog at Hanyi highway.

Climate trend rate and M-K mutation test methods are applied to analyze trends and mutation characteristics of temperature and precipitation in Jiangxi during 1951~2012. “Climate-economy” model is established to study the effect of climatic factors on rice yield. Finally, BP neural network model is used to predict the contribution of climatic factors to rice yield in the next 10 years. The results showed that temperature increased at a rate of 0.172℃/10a over the past 60 yearsbut linear trend of precipitation was not significant. Mutation of temperature occurred in 1997. Mutation of precipitation was not obvious. There were differences between contribution and direction of climatic factors action at different stages. The contribution of climatic factors was 5.97% during 1978~1997, in which the contribution of temperature and precipitation was 1.51% and 4.46%. The contribution of climatic factors was 8.98% during 1998~2013, in which the contribution of temperature and precipitation was 4.63% and 4.35%. The contribution of material elements was above 70% in different stages, including a large degree of plantings and fertilizer. The contribution of temperature to rice yield in Jiangxi province was 1.48 and the contribution of precipitation was 2.22 over the next 10 years.

Around the Erhai region in Yunnan province as multiple composite characteristics of typical area, have plateau lakes ecologically fragile area, ethnic culture diversity area and rural economic development active region at the same time, and it is also a vulnerable area of climate change. The annual average temperature, extreme maximum temperature and extreme minimum temperature, precipitation, maximum daily precipitation and precipitation days over 0.1mm of six stations around the Erhai lake area from 1951 to 2014 data as the foundation data are adopted. By linear trend estimation, Mann-Kendall trend test, Morlet wavelet analysis and R/S analysis method, climate change law was studied. It showing that: since 1951, the annual temperature and extreme minimum temperature were showed a rising trend, while extreme maximum temperature showed reducing trends, the change rate were 0.07/10a, 0.03/10a and 0.14/10a, respectively. The annual precipitation, maximum daily precipitation and precipitation days, are reduced trend, the rate is 12.85mm/10a and 1.73days/10a respectively. Annual average temperature, extreme high and extreme low temperature changes were not mutate, annual precipitation and precipitation days in 2010 there was a mutation decrease, while the maximum daily precipitation detected no year of mutation; Around the Erhai lake regional annual average temperature and annual precipitation have long time scales of the most significant cyclical change, with 30 years and 33 years respectively; and throughout the study period, local characteristics of periodic change of the short time scale is outstanding. From the point of future evolution trend, the annual average temperature and extreme minimum temperature will keep warming trend, while the extreme maximum temperature will continue to reduce, and continue reduce trend to increase trend of annual precipitation probability is smaller, while the probability of both the maximum daily precipitation and precipitation days will continue reduce trend are significant.

The accurate estimation ofaerodynamic resistanceis the key tosatellite retrieval of surfacesensible heat flux at present. In order toaccurately retrieve surface heat fluxin the Southeast Tibet, the validity of the commonly usedaerodynamic resistance models which are Thom (1975, 1977) and Choudhurymodels are analyzed by using the boundary layer observation data of grass, wheat, beach, forest shady and sunny slope in Linzhi on June 10, 2013. The results show that the estimated values of Choudhury model are consistent with the results of eddy correlation measurements on the forest shady slop and Thom (1975) model is recommended for the other underlying surfaces.

Carbon cycle or carbon balance is altered by human activities and carbon storage, especially soil organic carbon storage has become the focus of the world. Therefore, predicting the future carbon storage and selecting proper regional development paths have immense values. By taking Chongming Island as an example, this paper predicts its land use demand from 2011 to 2030 using the SD model, and then simulates landuse spatial distribution by the CLUE-S model. Finally, this study investigated the effect of land use changes on carbon storage under three development scenarios. Total population, GDP, urban construction land, agricultural land, forest and orchard land, urban green land, water and swamp area and other land are the level variables of the SD model. Remote sensing data of 2000, 2005 and 2010 years and statistical data of Chongming County Statistical Yearbook are the basic data of the paper. Testing stage of the SD model is from the year 2000 to 2010 and simulation stage is from 2011 to 2030.Based on the trend of historical development and some regional future plans, three scenarios (L, A and H) have been built up in the next decades. L means the development pattern with a low developing speed, A means the economic development pattern at a current developing speed, and H means the development pattern with a high developing speed. There are 12 driving factors in the CLUE-S model such as the distance of main towns, important towns, rural settlements, main roads, secondary roads, main rivers and wetland reserves, per capita GDP, population density, urbanization level, road density and river density. The results of logistic regression are used to check the availability of driving factors and land-use spatial distribution, which indicates that the value of ROC is appropriate. The results reflect that total soil carbon storage declines slowly and the decreasing rate is 1.40% and 1.32% from 2010 to 2020 and 2020 to 2030 during the study periods, respectively. The influence of human activities on the total soil carbon reserves is weak, but the influence of one single land use type is serious. For instance, in the H scenario, the declining rate of total soil carbon storage is 2.72% from 2010 to 2030,while the decreasing rate of carbon storage in agricultural land and forest and orchard land is 30.13% and 126.60%, respectively. L scenario is selected as the better development pattern with the largest total soil carbon storage. L, A and H scenario in 2030, the soil carbon storage of which are 3093.03×10⁶kg, 3079.47×10⁶kg and 3059.81×10⁶kg, respectively. It is reasonable and practical to simulate and calculate the ecosystem carbon storage by the coupled SD and CLUE-S models in both temporal and spatial scales. This paper then proposes some useful suggestions to reduce the impact of human activities on soil carbon process, such as strengthening farmland protection, promoting forest construction and improving land-use structure.

In this study by using the surface observation data (1961-2013) collected from 146 meteorological stations of the Yangtze River Delta, the seasonal characteristic of haze over the Yangtze River Delta in a recent 53 years were analyzed. The results indicated that the frequent periods of haze days have been spreading from winter to spring, autumn and even summer. The seasonal change rate of haze days in 1960s-1970s was up to 72.5%-78.5%, dropped to 61.2% in 1980s and 55.3% in 1990s, while in recent 13 years of this century was as low as 52.3%, which indicated that the seasonal differences of haze days have stable declined. Haze pollution, previously happened in winter in the Yangtze River Delta, has tended to be a frequently occurring phenomenon in all over the year. The analysis on the inter-annual and spatial variations of haze over the Yangtze River Delta in different seasons also indicated that haze days averaged over the Yangtze River Delta exhibited an increasing trend during the past 53 years, and grew slowly and maintain little haze days level before 1980, and grew slowly after 1980 but maintain more haze days levels. The regions with high frequent haze are centered over Nanjing- Zhenjiang area, southwest Shanghai, Huzhou-Hangzhou-Shaoxing-Jinhua area, and the northwest area of Ningbo city. The highest numbers of haze days in the 53-year average reached to 70.2, 40.0, 38.0, 35.5 days per year for Lanxi city in Jinhua, Nanjing city in Jiangsu, Jinshan district in Shanghai, Yuyao city in Ningbo, respectively. In terms of the geographical distributions of inter-annual variability rate of haze, central Yangtze River Delta area experienced the lower inter-annual variation rates than south Yangtze River Delta area and north Yangtze River Delta area. The large inter-annual variations of haze days concentrated over the central and south Jiangsu, the south Zhejiang and east Zhejiang coastal, as well as southeast Anhui. Seasonally, the inter-annual increase rates peaked in summer, and then followed by autumn and spring, and inter-annual increase rate in winter reached lowest in most of the Yangtze River Delta. The decreasing seasonal difference of haze is exhibited in most areas of Yangtze River Delta over the recent 53 years.

In order to reveal the spatial distribution and bio-availability of nitrogen speciation in sediments of Danjiangkou Reservoir, the exchangeable nitrogen (EN), the acid hydrolysable nitrogen (HN) and the residue nitrogen (RN) in the surface sediment were analyzed by sequential extraction method. The results show that TN in the Danjiangkou Reservoir was 425-5796 mg/kg, with the mean value of 1319.32 mg/kg, the average value of EN, HN and RN relative proportions is 2.15: 1.95: 1, and the spatial distribution of various forms of nitrogen content in warehousing river is higher than the reservoir, especially in Danjiang, Laoguan river and the mouth of Jiang river - Du river. Nitrogen mineralization potential was 40.20-1468.95mg/kg, with the mean value of 275.06 mg/kg; the exchangeable nitrogen's contribution to the danjiangkou reservoir sediment PMN is bigger, ratio between 19.85%-90.80%, with the average of 63.47%. Migration and transformation of different forms of nitrogen happened in different water environment conditions, keeping dynamic balance between water and sediment.

The Yangtze River Economic Zone is one of three pillars of China's economy. The successful implementation of carbon emission reduction in the Yangtze River Economic Zone is important to the construction of ecological civilization in China. In this paper we used social and economic data and data of energy consumption in the Yangtze River Economic Zone (including 9 provinces and 2 municipalities) during 2005-2013, and statistical analyses to quantify carbon emission, per capita carbon emission, energy intensity, evolution of industrial structure diversification degrees and the their rate of change. By using the elastic computing and matrix classification methods, we quantified the spatial and structural differences in carbon emission of the Yangtze River Economic Zone. The results showed that: (1) Yangtze River Economic Zone's carbon emission and its growth rate, per capita carbon emission and its growth rate, and energy intensity were all higher than the national average level. While the rate of reduction in energy intensity was lower than the national average level. If we divide the Yangtze River Economic Zone into eastern, middle and western regions, the total amount of carbon emission, per capita carbon emission and energy intensity rate all declined in gradients; while the growth rate of carbon emission, the growth rate of per capita carbon emission and energy intensity all increased in gradients. (2) The regions that began industrialization earlier, and were transformed from heavy-industry-oriented to service-industry-oriented faster and more fully, will have higher level of low-carbon economy. Increase in the speed of industrial structure diversification degree is positive to the carbon emission reduction. (3) Different regions of the Yangtze River Economic Zone should use different measures to achieve carbon emission reduction targets. The eastern region should focus on reducing carbon emission per capita, the middle region and the western region should focus on reducing energy intensity. (4) Future carbon emissions reduction measures should focus on both fairness and efficiency, and the targets of carbon emission reduction should be allocated in accordance with financial capability of each region, carbon sink capacity, production efficiency, energy structure and other factors.

The Yangtze River, one of the longest rivers in China, plays an important role in the development of national economy. To understand chemical characteristics and its controlling factors of the Yangtze River, 42 samples were collected from the Yangtze River and its main tributaries during the period of high-discharge in July and August, 2013. The major ions of the water samples such as K⁺, Na⁺, Ca²⁺, Mg²⁺, HCO₃^-,SO₄^2- and Cl^- were analyzed, as well as hydrogen and oxygen isotopic compositions (δD and δ¹⁸O). The δD and δ¹⁸O values of the Yangtze River ranged from -106‰ to -31‰ and from -14.6‰ to -4.1‰, respectively, located around the local meteoric water line (LMWL), indicating that atmospheric precipitation is the main source of the river in the wet season. The chemical type of the Yangtze River was mainly represented as HCO₃·SO₄-Ca, associated with chemical weathering of carbonates distributing widely in the drainage basin. The median of the total dissolved solid was about 242 mg/L, three times of the world average level. The pH values and concentrations decreased from the upper reaches down to the lower reaches along the Yangtze River, whereas both SO₄^2- and Ca²⁺ concentrations increased. The most significant factor controlling variation of the chemical composition of the Yangtze River, in wet season of 2013, was the dissolution of soluble salts contained in the surrounding rocks and the influence of human activities. The second potential affecting factor was chemical weathering dissolution of carbonate accelerated by acid rainwater in the upper Sichuan and Guizhou areas and the lower Yangtze River Delta and acid waste drainage by human activities. The dissolution of silicate minerals and associated weathering products was another possible affecting factor for chemical composition of the Yangtze River. The research can help better understand water quality and its evolution trend of the Yangtze River, and provide a scientific basis for assessment and management of water resources in the Yangtze River Basin.

Through the research on interaction between people and infected water and schistosomiasis control, it can promote a steady and healthy social economic development in the Dongting Lake Area. Based on the hydrological conditions, industry development, residents' behavior, urban and rural construction four aspectswe discussed the interaction between people and schistosomiasis infected water in the Dongting Lake Area. By using the system dynamics model, we set up an education priority program, an ecological protection priority program and a urbanization promoting program to make the system simulation and comparison analysis. The results show as follows. (1) Eco-hydrological factors that influence the human contact with water gradually reduced, and the socio-economic factors are becoming increasingly important. (2) The system dynamics model can effectively show the relationship between various influencing factors of schistosomiasis, and it is one of the effective methods to study the prevention and controlling of schistosomiasis epidemic. (3) Based on simulation results, the urbanization promoting program is the optimal prevention and control program for economic growth, urban and rural coordination, environment-friendly development.

Droughts and floods are the most severe disasters in China, featuring wide spread, high occurrence and tremendous economic damage. Based on the analysis of documentation and observation data, the inter-decadal changes of drought-and-flood in south China indicated that the yearly and inter-decadal changes of d-and-f disaster have been becoming more and more obvious corresponding to the process of global warming. Jiangxi province is located in the central area of southern red soil region. In recent decades, Jiangxi suffered from the harm of frequent droughts and floods. Moreover, Jiangxi is one of the provinces famous for its farming production. Therefore, frequent droughts and floods have resulted in enormous economic losses in this region. Hence, studies about the inter-annual variation of droughts and floods in Jiangxi province are helpful for the early warming of droughts and floods. In this study, the monthly mean meteorological data during 1961-2010 including monthly mean temperature, maximum temperature, minimum temperature, relative humidity, wind speed and sunshine data in five meteorological stations such as Ganxian, Ji'an, Nancheng, Nanchang and Jingdezhen in Jiangxi province were collected from China Meteorological Data Center (CMDC). Based on these data, reconnaissance drought index (RDI) was adopted and calculated and the changes of droughts and floods in Jiangxi in recent fifty years (1961~2010) were looked into with the help of the Mann-Kendall test. Moreover, main driving factors for such changes in droughts and floods have been investigated with the help of multiple regression analysis method. The results suggested that an increase break point of the inter-annual scale RDI_st value of Jiangxi province occurred in 1969 years during 1961-2010, suggesting that the drought level increased but flood level declined during this period. It was indicated that an increase break point of the RDI_st value in spring occurred in 1967 years, indicating that the drought level gradually increased but flood level gradually decreased in spring in Jiangxi province since 1967 years. It was suggested that an increase break point of the RDI_st value in fall occurred in 1971 years, indicating that the drought level gradually increased but flood level gradually decreased in fall in Jiangxi province since 1971 years. No break points existed in the RDI_st value of Jiangxi province in summer and winter during 1961-2010 as indicated by the Mann-Kendall test, which suggested that drought level or flood level in summer and winter during 1961-2010 showed no increasing or decreasing trends. The inter-annual scale or seasonal-time scale of RDI was significantly positive correlated with rainfall and relative humidity, but negative correlated with sunshine (p < 0.01). The contribution rates of rainfall to the changes in droughts and floods were highest, accounting for 42%~58%, followed by mean temperature and relative humidity accounting for 11%~19% and 7%~19%, respectively. The contribution rates of mean wind speed and sunshine to the changes in droughts and floods were small. Inter-annual scale and spring standardized RDI displayed an increasing trend during 1961~2010, caused by increases in rainfall and relative humidity and decrease in sunshine. However, summer, fall and winter standardized RDI showed no increasing or decreasing trends during 1961~2010.

The soil erosion and ecological benefits in the water source region of middle route of South-to-North water transfer project were evaluated by using soil erosion coefficient and soil conservation coefficient based on USLE. The results show as follows. (1) The potential amount of soil erosion in the study area was large, and showed significant difference in spatial distribution. It was larger in the middle and high mountain region than that in the valley basin region. (2) The actual amount of soil erosion was lesser. However, the soil erosion coefficient was large with the obvious spatial distribution regularity. It was the largest in low mountain area and hilly region, and was relatively smaller in the middle and high mountain region and the valley basin region. Soil and water conservation measures and land use patterns have the high contribution to soil erosion. (3) The benefit of soil and water conservation was increased in the middle and high mountain regions, but was obviously decreased in the valley basin region, low mountain area and hilly regions. (4) The low mountain area and hilly regions should be the key monitoring and control area in the future soil and water conservation, and it should be the key ecological compensation area also.

The downstream of the Funiu River was flooded frequently by rainfall and the backwater of the Yangtze River flood. In order to assess the effect of the midstream and downstream controlling flood in the Funiu River, and analyze potential submerged risk of coastal engineering structures in rainstorm period, the study simulated water depth and submerged area of midstream and downstream in different rainstorm return period by using MIKE11. The results showed that average water depth was 4.9 meters in midstream under the rainfall of 50-year return period. And the submerged area was 40 542 square meters. While under the rainfall of 100-year return period, the average water depth became 5.7 meter and the submerged area became 41 980 square meters. Meanwhile, the rainstorm would inundate the residential land at Aoshan integrated market. Besides, farmland would be submerged which located in steady slope by river bank. Under the backwater of the Yangtze River flood, water depth was 7.5 meter and flooded area was 9 890 square meters in downstream on once fifty years backwater. The two values were 8.9 meter and 10931 square meters at the 100-year return level of backwater. Moreover, residential buildings and wastewater treatment plant would not be affected. However, considered the Yangtze River flood season happened to wet period of the Funiu River, it's necessary to combine the influence of rainstorm and the Yangtze River backwater. The specific numbers were 9.4 meter for average water depth and 14 559 square meters for submerged area at the 50-year return period. And there were 10.1 meter and 16 987 square meters at the 100-year return period. What's more, under the both influence of rainstorm and the Yangtze River backwater, the wastewater treatment plant and some residential buildings would be drowned in downstream. These provided references of flood control planning and coastal engineering construction in the Funiu River. For midstream, flood control levees should be constructed, especially in flat river bank. When making flood prevention plan, it would be better to improve flood control standard for the safety of construction projects. On the other hand, the basement and side slope should be strengthened in downstream residential buildings, road as well. In addition, the wastewater treatment plant should be protected by bulwark or relocated.

Since the super earthquake happened on May 12^th 2008 in WenChuan, ecosystems in WenChuan have significant been affected. The purpose of this research is to provide strategical supports for medium to long term ecological recovery monitoring ecological restoration. and three different time periods were assessed, including 2007 (before earthquake), 2009 (after earthquake), and 2013(restoration). The research adopts a lot of index number such as sensitivity of soil erosion, canopy interception, and suability of habitat condition to assess the status change among function of water and soil conservation, water conservation, and species diversity ten areas that were severely afflicted areas. The result shows that water and soil conservation, water conservation, and species diversity protective functions have been destroyed in study area after the earthquake. Overall, after five years to some extent the ecological service in the study area has recovered, while it was still short of the standard before the earthquake. Six cities (Wenchuan, Dujiangyan, Shifang, Pengzhou, Mianzhu, Anxian) located in central-south were have high degree of damage compare to other four cities. These areas are the dynamic districts of debris flow and landslide. Due to large amount of rainfall after the earthquake, landslide and debris flow caused the recovery rate of water conservation function and species diversity protective function decreased; including Caoping village, Yinxin village, and Gengda village, Wolong village, and Sanjiang village. In addition, the function of water conservation and species diversity protective function in Dujiangyan, Pengzhou, Shifang,Mianzhu, and Anxian were also slight declined. Although, the reconstruction of post-disaster to some extent has changed ecological function status and improved ecological function recovery progress, less maintained attention to ecological function recovery would become a problem to the whole project progress. For example, enforcement project of post-disaster reconstruction causes the ecological service function degraded in local area. Therefore this research provides two recommendations: 1) reinforcement of medium to long term ecological recovery remote sensing and ground monitor, as well as to provide the assessment of the effect of ecological function recovery in study area; 2) reinforcement of ecological restoration in key areas such as drought river- valley, Longmen Mountain, and Chaping Mountain etc.
