GIS-based ecological sensitivity evaluation of Dongting Lake in China

Applying the remote sensing images of Dongting Lake Basin in China the field survey, and socio- economic data, the ecological sensitivity comprehensive system was established to analyze the environmental sensitivity of Dongting Lake Basin under the support of geographic information system (GIS) and AHP and entropy weight method. The results suggest that the ecological sensitivity of Dongting Lake Basin was at a mild sensitive level, with almost higher sensitive regions focused on the river network, mainly from human activities and economic growth. This study revealed the ecological and environmental health status of Dongting Lake Basin and provided a theoretical basis for ecological and environmental protection, social and economic layout, and ecological civilization construction.
