Study on the Measurement Index System of Green Development Degree in Coal Mining Area Based on Comprehensive Environmental Capacity

Green development is the inevitable choice on sustainable development of Shaanxi province in coal mining area. First, the environment capacity of coal mining area is defined from the point of view of comprehensive environmental capacity, which expounds the scientific connotation in the particularity of the coal mining area and coal industry. On this basis, three the key affecting factors of carrying capacity of environment in coal mining area are selected, which are mining subsidence, damaged shallow groundwater, and industrial "three wastes" pollution. Second, from the point of he comprehensive environmental capacity, the measurement framework of green development degree in coal mining area is built. And it takes the key affecting factors as the subsystem. On this basis, the measurement index system of green development degree in coal mining area is established. And it has 9 first grade indexes, which are ratio of rock and mining, form of surface subsidence, buried depth of ecological groundwater, space relationship of diversion fissure zone and key to aquifer, the capacity of regional atmospheric environment, the capacity of regional water environment, waste emissions, vegetation coverage, soil erosion modulus. At last, this paper is using the AHP method and entropy method to establish the measure indication system of green development degree on coal mine area in Northern Shaanxi.
