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.As the quality of mines is large and poor concentration, taking 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, a total of 16 indexes.The study area is divided into 196 evaluation units with 4 km×4 km and the data can be obtained by field investigation and statistical yearbooks.Evaluation indexes weights are calculated by entropy method through SPSS20.0 software, and using it to calculate connection degree of each evaluation unit.Finally, the mine geological environment quality area is divided into “serious area”“general area” and “good area” by connection degrees.The results show that spatial distribution of mine geological environment quality in Shangnan county is quite different.The quality of mine geological environment in the central and north of study area is obviously superior to that in the south.The problems of mine geological environment are mainly geological hazards, land occupation, vegetation destruction and soil-water pollution, concentrating in Shuigou town, Xianghe town and Zhaochuan town.The “Serious area”“general area” and “good area” each occupied 8.16%, 46.95% and 44.89% of study area.Evaluation results can provide theoretical basis for comprehensive management of mine geological environment in Shangnan county.
