Research On The Mine Geological Environent Evaluation Of Shilin Yi Autonomous County In Yunnan Province

Shilin Yi Autonomous County has a rich and profound minority culture,the world's natural heritage Shilin Geological Park is located in the county,tourism and cultural resources is extremely rich.The integration development of national culture and tourism industry has greatly promoted the local economic development.However,in recent years,with the increasing demand for mineral resources,the development of excessive mineral resources has caused more serious problems of mine geological environment,which has stimulated the contradiction between tourism and environment in Shilin Yi Autonomous County.Therefore,We carry out the evaluation of mine geological environment,determine the different quality partition of mine geological environment,and put forward effective governance and protection measures according to the problem of mine geological environment of different partition,which is an important measure to realize the reasonable exploitation and utilization of mineral resources and to protect the geological environment.This paper applies high-resolution remote sensing image data and tenement data,I analyzes the geological background,the development status of mineral resources and the main mine geological problems in Shilin Yi Autonomous County,constructs the evaluation index system of mine geological environment in study area based on ArcGIS10.2 technology platform.Using expert scoring method to determine the evaluation index classification,AHP decision analysis method to determine the evaluation index weight value.Finally,evaluating the mine geological environment using the comprehensive evaluation model of weighted index in the study area.According to the evaluation results,the study area is divided into mine geological environment quality poor area,relative poor area,general area and excellent area.Among them,there are 47 excellent areas,which accounts for 78.56%of the entire study area;106 general areas,which accounts for 13.42%of the entire study area;70 relative poor areas,which accounts for 5.19%of the entire study area;47 poor area,and which accounts for 2.83%of the entire study area.Finally,we can put forward the countermeasures and suggestions for the protection and restoration of mine geological environment zoning through the empirical analysis on the geological environment partition.We can find out that the evaluation results are in line with the actual situation of the study area by field verification,which indicate the construction of the evaluation index system,the selection of evaluation method and evaluation model are feasible.The research results have important practical value and theoretical reference value for guiding the sustainable development and utilization of mineral resources in Shilin Yi Autonomous County and the evaluation of mine geological environment in other areas.
