摘　　要：目的:长期不合理利用矿山资源导致水土流失、耕地面积减少、生态系统被破坏。为了合理利用矿产资源,恢复治理矿山地质环境,以湘西北为研究对象。方法:通过考虑三种评价类型八个评价因素(人口密度、地表坡度、降雨状况、工程岩组、地质构造、矿山占地、地质灾害、森林覆盖率),对其进行专家评估权重评估,经过计算得到Q值,创新之处是运用矢量多边形法叠加GIS分析开展本地矿山地质环境评价工作。基于地理信息系统技术进行制图,对研究区各区县矿山环境等级定级。结果:直观的评价湘西北区域矿山环境一般。意义:可为湘西北矿山环境管理以及生态修复提供一定的参考依据以及其他矿山评价提供理论依据。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.
