Abstract:Purpose: Long-term irrational use of mine resources leads to soil erosion, the reduction of cultivated land area and the destruction of the ecosystem. To make rational use of mineral resources and restore and control the geological environment of mines, the northwest of Hunan Province is taken as the research object. Method: The methods are as follows: By considering eight evaluation factors of three evaluation types (population density, surface slope, rainfall, engineering rock group, geological structure, mine area, geological disaster, and forest coverage rate), the expert evaluation weight was evaluated, and Q value was obtained through calculation. The innovation was to carry out local mine geological environment evaluation by using vector polygon method and GIS analysis. Based on geographic information system (GIS) technology, the mining environment of each district and county in the study area was graded. Result: The results showed that the mining environment in the northwest Hunan region was generally evaluated intuitively. Significance: It could provide a certain reference basis for mine environmental management and ecological restoration in northwest Hunan Province, and provide theoretical basis for other mine evaluations.
