Abstract

Based on remote sensing images, field investigation and socioeconomic data, as well as the environmental characteristics, this study constructed an index system of ecological sensitivity evaluation for the Yangtze River Delta from seven aspects: soil erosion, geomorphology, wetness, habitat, water environment, human interference, and climate. Through the Coefficient of Variation method and GIS techniques, the ecological sensitivity of the Yangtze River Delta was divided into five levels: extremely sensitive, highly sensitive, moderately sensitive, mild sensitive, and insensitive. The analysis results show that there are differences in the spatial distribution of ecological sensitivity in the Yangtze River Delta. The areas of extremely sensitive, highly sensitive, moderately sensitive, low sensitive and insensitive are 16817km2, 25280km2, 33579 km2, 20177 km2, and 14693 km2, accounting for 15.21%, 22.87%, 30.38%, 18.25%, and 13.29% of the total area, respectively. Consequently, environmental conservation strategies for the Yangtze River Delta are suggested for future urban development and construction.
