|Abstract:Shangnan County is rich in mineral resources, mining development is the pillar industry of the county. Frequent mine construction and mining activities is one of the reasons that lead to geological environmental problems occurred frequently in the county. As the quality of mines is large and poor concentration, the article takes Shangnan country as the research area. The evaluation index system of the article is built that contains the influence of mining development on geological environment, basic geology and ecological environment occupation, a total of 15 indexes. The study area is divided into 196 evaluation units with 4Km×4Km, through field investigation, statistical yearbook and other ways to obtain data. Evaluation indexes weights are calculated by entropy method through SPSS20.0, and using it to calculate contact degree of each evaluation unit. Finally, the mine geological environment quality area can be divided into "serious area", "general area" and "good" by the contact degree. The results shows that the spatial distribution of mine geological environment quality in Shangnan County is quite different. The quality of mine geological environment in the central and northern of Shangnan County is obviously superior to that in the south, and the problems of mine environment in the south are mainly concentrated in Shuigou Town, Xianghe Town, Zhaochuan Town and so on, the mainly geological environment problems are occupy ditches, destroy vegetation, soil and water pollution. The "Serious area", "general area" and "good area" each occupied 7.14%, 51.53% and 41.33% of the study area. The evaluation results can provide theoretical basis for comprehensive management of mine geological environment in Shangnan county.
