With the rapid development of economy in China, the social demand for resources is increased day by day, the ecological environment is seriously damaged by large-scale development of mineral resources, and the ecological environment restoration becomes a common demand of economic development and social progress. In recent years, relevant departments such as the ministry of the state and the ministry of the county have established ecological protection and compensation economic mechanisms of resource development, promote special treatment of resource-depleted cities, develop actions of 'mine greening', build national mine parks and the like, and obtain stage results. However, in general, the geological environment recovery and comprehensive treatment of the mine in China still do not adapt to the new trend requirements, and the damaged land area of 220 million hectares in China is not effectively treated at present. Therefore, the ministry of land resources makes a plan, and the goal of mine ecological restoration is to complete 50 ten thousand hectares of land treatment in the thirteen-five period, and the estimated capital investment is 750 billion yuan.
