基于灰色关联分析法的江西省矿山环境质量评价

矿山环境质量评价是环境保护领域中带有方向性并颇具实践意义的工作。科学客观的评价结果可指导矿山环境保护与治理决策,促进矿业资源合理开发。不同矿山所处的开发阶段不同,其存在的环境问题也复杂多样。对数量庞大的多个矿山进行环境质量评价,灰色关联分析法具有较强的实用性。EXCEL数据处理功能的运用,弥补了灰色关联分析法中样本数量不足的缺陷。本文以江西省矿山环境质量评价为例,进行了矿山环境问题成因分析,系统阐述了采用灰色关联分析的评价方法与模型。选取了矿山环境背景和危害两大类共12个评价指标,以全省总矿山为样本评定了各指标作用权重和质量分级,结合综合指数法确定各矿山环境质量等级,为矿山环境保护与治理规划提供了可参考的科学依据。

Mine environmental quality evaluation by grey relational analysis method in Jiangxi Province

Mine environmental quality evaluation is a work that has orientation and practical significance in the field of environmental protection.A scientific and objective evaluation result not only can guide the mine environmental protection and treatment policy,but also can promote the rational exploitation of mineral resources.Because different mines are in different stages of exploitation,their environment problems are complicated and various.The grey relational analysis method is very practical in environmental quality evaluation for a huge amount of mines.In this paper,the authors use EXCEL data processing to remedy the defect of limited samples in the grey relational analysis method.Taking mine environmental quality evaluation in Jiangxi Province as an example,this paper analyzes the cause of mine environment problems and makes a systematic discussion on the method and model of evaluation based on the grey relational analysis.12 evaluation indexes related to environmental background and environmental damage of the single mine are selected to evaluate the weights of indexes and quality grading taking all the mines in Jiangxi Province as examples,and in combination with the comprehensive index method,the mine environmental quality grades are determined for various mines,respectively,thus providing a scientific basis for mine environmental protection and control.
