摘　　要：矿产资源的开采在繁荣经济的同时对生态环境造成影响,如何正确的评价矿山环境是目前研究的重要课题。以江西省萍乡市为研究区,依据该市的矿山地质环境遥感调查结果,结合相关背景资料,建立评价指标体系,采用层次分析法计算指标的权重。根据矿山地质环境特征,对物元可拓方法在关联函数以及评价尺度上的局限性进行改进。为验证改进的物元可拓模型的可行性,采用模糊综合评价法对其进行验证,结果表明,改进的物元可拓模型可用于矿山环境评价,评价结果可为萍乡市矿山环境治理提供依据。The exploitation of mineral resources has a certain impact on the ecological environment while prospering the economy.How to correctly evaluate the mine environment is an important topic of current research.Taking Pingxiang City of Jiangxi Province as the research area,based on the remote sensing survey results of the mine geological environment in the city,combined with relevant background data,an evaluation index system is established,and the weight of each index is calculated by the analytic hierarchy process.According to the characteristics of the geological environment of the mine,the limitations of the matter-element extension method on the correlation function and the evaluation scale are improved and used in the environmental assessment of Pingxiang City.In order to verify the feasibility of the improved matter-element extension model,it is verified by the widely used fuzzy comprehensive evaluation method in the mine environment evaluation.The result shows that the conclusions obtained by the two methods are basically the same.The improved matter-element extension model in some subtleties is more in line with the actual situation,which proves that the improved matter-element extension model can be used for mine environment evaluation,and the evaluation result provides a basis for the governance of the mine environment in Pingxiang City.
