Abstract: In this paper, remote sensing technology has been applied in monitoring of the land cover variation, detection of water depth and distribution as well the eutrophication of water environments in subsided water-accumulating area in past 20 years on the basis of the multi-temporal remote sensing images. The results show that the subsided water-accumulating area has reached 22.23% of the total study area in 2012, the maximum water depth is over 4 meters, and the water is at slight to moderate eutrophication level. According to local conditions and reasonable development, we divide the subsided water area and propose an comprehensive restoration model of ecological environment, which would emphasize on the establishment of ecological agriculture, integration of landscape of wetlands, entertaining and regulation and storage functions in the coal mining.-induced subsidence area.
