Abstract :
Mining exploration destroys the soil structure, vegetation coverage, landform and physiognomy, especially, the non-renewable soil layer. It has greatly hindered the sustainable development of the mining area and caused great losses. Based on existing soil erosion data, contradictory problems between the mining exploration and soil degradation were analyzed. The basic data was obtained using GIS and RS technology and the risk assessment of soil erosion was done by the extension theory model. Comparing the extension theory model and digital model with GIS technology, the extension model is more scientific than the digital model. Unfortunately however, it cannot combine the spatial and attribute data, and its evaluation factors also need further research.
