Analyses the relationship between urban dynamic change pattern of the Yangtze River delta and the ecological environment

We are using multi-temporal remote sensing image: TM image to analyse the spatial and temporal urban dynamic change pattern of Yangtze River delta region in the past two decades. Combined with the social and economic database of China, we analyses the relationship between the urbanization and society, environment. The results imply that from end of 80´ to 2000 year, the main land use change pattern is the cultivable farmland and forest area decreased rapidly, urban area increased quickly spatially to joint to each other. The power reason for this transform are the development of the third industry mainly including traveling, lots of foreign investment entering in this area, increase of urban population, and fluctuation of the agriculture produce price. Going with this change the ecological environment problem became serious.
