摘要/Abstract

摘要： 基于第一次地理国情普查数据,以浙江省德清县为例,探讨县域单元美丽乡村建设类型划分和生态廊道建设。首先,基于自然本底,将村域单元划分为3种类型:山地景观型、丘陵风光型和平原水乡型;在此基础上,考虑城市未来扩展空间,增加都市风貌型,最终将美丽乡村建设划分为4种类型。其次,依据资源空间分布,评价各个村域单元美丽乡村建设潜力,将所有村域分为3个等级:核心建设村落、重点建设村落和一般建设村落。第三,识别出对德清具有重要生态意义的6个生态保护区,考虑不同地表覆盖景观格局对动物迁移的阻碍差异,利用GIS空间分析方法,计算出迁徙成本最小的路径,识别出4条重要的生态廊道。第四,将识别的生态廊道与地表覆盖进行匹配调整分析,最终构建起德清县“六核心、四廊道”的生态空间格局。

Abstract: Developing ecological civilization and building a beautiful China urgently need to focus on rural development. It is also need to promote the construction of the beautiful village with considering local conditions. In the past, many researchers focused on the system level of beautiful village construction, and neglected the spatial level. Based on geographic conditions survey data, taking Deqing County which locates in Zhejiang Province as an example and using spatial analysis technology, this paper discusses the orientation choice and corridors construction of beautiful village construction.#br#Firstly, natural background, especially topography and water, is a major factor to construct beautiful village. Based on natural background, the construction orientation could be divided into three types in village level: mountain landscape orientation, hilly scenery orientation, and plain and water orientation. Then, considering urban space expansion in the future, urban landscape orientation is added. Four types of orientation are divided in the finally: mountain landscape orientation, hilly scenery orientation, plain and water orientation, and urban landscape orientation.#br#Secondly, differences in resources endowments influence development potential of beautiful village construction. These resources can be reduced into 3 types: tourism resource, culture resource and current situation of beautiful village construction. Based on the distribution of resources, the potential of beautiful village construction of each unit has been evaluated. All villages have been divided into three grades according potential evaluating: core construction villages, important construction villages and general construction villages. The villages with Good potential mainly distribute in 3 areas: west mountain area, near the Xiazhu Lake area and northern area of the county.#br#Thirdly, six ecological protection zones which are important for ecological security in Deqing are identified. In different land cover regions, the obstacles of animal migration are not the same. Using the costdistance algorithm which can be run in the software of ARCGIS, this paper calculates the migration cost of six ecological protection zones. Then, based on this migration cost, using the shortest path algorithm, we calculate the minimum cost migration paths. Four important ecological corridors have been identified.#br#Fourthly, we add the ecological corridors to land cover, and adjust the space position of ecological corridors. The ecological spatial pattern which includes six core ecological protection zones and four ecological corridors has been built in Deqing County. In the process of economic development, the core ecological protection zones and ecological corridors should be protected. Such protection is very important to maintain ecological security in Deqing County.

Key words: beautiful village, types division, grade evaluation, ecological corridors, Deqing County
