Land Destruction Extent Assessment Based on RS and GIS in Liaoyuan Mining Area, China

The aim of this paper is to quantify and visualize the extent of the land destruction caused by the mining activities. Taking the surface deformation, the damage area, the pollution condition and the hydrological feature as main factors, this article used the analytical hierarchy process to select the associating indexes and applied the fuzzy mathematics comprehensive evaluation model to quantify the land destruction extent in Liaoyuan mining area, China. The result showed that the land in Liaoyuan were divided into four degrees, which are the severely destructed zone, the moderately destructed zone, the lightly destructed zone and the none destructed zone. The land reclamation strategies suitable for four different zones were suggested in the last to guide the future land use planning and policy in Liaoyuan mining area.
