Abstract:

Using the land use database from National Land Investigation and spatial analysis software (ArcGIS 93), combined with a landuse dynamic model, this paper analyzed the spatialtemporal characteristics of the urbanrural land use changes in Wuhan City during 1996-2009. The results showed that the scale of urbanrural construction expanded so rapidly that the amount of cultivated land decreased drastically during this period in Wuhan city. Compared with the expansion rate, the urban construction land was growing fast, followed by the expansion of rural construction lands, which was slow but seriously occupied the cultivated land. With the total growth of the urban construction lands, the increasing rate of the town was much faster than the city; and the independent industrial and mining lands decreased in each year. The increasing area of the city and the town was mainly from occupation of the agricultural land, conversion of the independent industrial and mining lands, and consolidation of rural residential areas. According to the spatial variations, the Wuhan city was divided into innercity and outercity. The expansion scale of the urbanrural land in outercity was larger than the innercity. The transference of quantity and category about various construction lands in outerurban played a decisive role in the urbanrural construction land change of Wuhan city. This paper extracted the driving factors of the land use policy and the ecological conservation policy on the urbanrural construction land from the land use conversion dates of Wuhan. Based on the related social and economic statistics data and information of Wuhan, the paper analyzed the driving force of urbanrural construction land change using the qualitative and quantitative analysis method. The results showed that the social and economic factors including demographic change, economic growth, living standards and policies were closely related to the urbanrural construction land use pattern. Because of the difference of economic and social development, there were significant regional differences and urbanrural differences on the quantity and structure change and the driving factors and mechanism between the innercity and the outercity of Wuhan. Based on the perspective of urbanrural integration, this study on the spatialtemporal characteristics and driving forces of urbanrural construction land changes in regional scale can provide important implications to regional urbanrural construction planning and the urbanrural integration development
