摘要
本文以湖南省宁乡县矿山地质环境调查资源为基础,选取矿山地质灾害危害程度、矿山土地资源破坏程度、矿山水土污染程度、矿山地下水系统破坏程度、矿山环境条件脆弱程度以及矿山环境恢复治理难易程度六个评估因子,采用综合指数评估法,对宁乡县矿山地质环境现状进行评估,结合各地域、矿区、段的开发利用强度,将宁乡县矿山地质环境现状划分为影响严重区、影响较严重区、影响一般区三个等级。
Based on the available mine geological environmental data of Ningxiang county in Hunan province,this paper selects six effect evaluation factors(mine geological hazard degree,mine land resource damage degree,mine water and soil pollution degree,mine groundwater system damage degree,mine environmental condition vulnerability and mine environment recovery and governance difficulty)to represent mine issues and conduct zoning evaluation on mine geological environmental situation of Ningxiang county by comprehensive index judgment.Combined with the development and utilization intensity of various regions,mining areas and sections,the current status of mine geological environment in Ningxiang county is divided into three levels:severely affected areas,more severely affected areas,and affected general areas.
