Evaluation and Analysis of Land Ecological Economic Benefit in Baodian Mining Area

Abstract

As a resource for human survival, coal and land carry thousands of years of production activities. With the improvement of the scientific level, the mining volume of coal has increased by year, and the contradiction between coal mining and land resources has been increasing. On the basis of studying the impact of coal mining on the ecological and economic benefits of land, the entropy weight method and the coupling degree quadrant identification method are used. Taking the assessment, and taking Baodian Coal Mine of Jining City as an example, through the analysis of the economic benefits and ecological benefits of the mining area in 2010-2018, the coupling degree of ecological and economic benefits shows a curve of “semi-inverted U”, which is in line with the mining area. The law of land use development, the ecological and economic benefits of Baodian Coal Mine are in a relatively coordinated development stage.
