酸性矿井水会对水环境造成严重污染,对遭受污染的矿井水质进行评价是矿山环境保护与治理的重要前提.因此,以贵州省内的酸性矿井水分布区为研究区,采用因子分析(FA)、模糊综合评价法(FCE)和加权平均法,并引入级别特征值构建了 FA-FCE水质评价模型,对矿井水质和水环境质量进行综合评价.结果显示,所评价的水样中V类水的占比达到70.37％,水质整体偏向于V类水,各地区的平均级别特征指数均大于2,矿井水水体环境遭受污染的程度较高.相较于传统的评价模型,文中提出的水质评价模型在选取评价指标及权重分配等方面有显著的优势,并综合考虑了所有评价指标在整体评价中的影响,使得评价结果更加科学合理.
Application of improved FA-FCE model in mine water quality evaluation
Acid mine water can cause serious pollution to the water environment,and the evaluation of mine water quality suffering from pollution is an important prerequisite for mine environmental protection and management.Therefore,this paper takes the distribution area of acid mine water in Guizhou province as the study area,and uses factor analysis(FA),fuzzy comprehensive evaluation(FCE)and weighted average method,and introduces the level characteristic value to construct the FA-FCE water quality evaluation model,and carries out a comprehensive evaluation of the quality of the mine water and the quality of the water environment.According to the results,the proportion of class V water in the evaluated water samples reached 70.37％,the overall water quality is biased towards class V water,and the average level characteristic value of each area is bigger than 2,and the environment of the mine water body suffers from a high degree of pollution.Compared with the traditional evaluation model,the water quality evaluation model proposed in this paper has significant advantages in the selection of evaluation indicators and weight distribution,and comprehensively considers the influence of all evaluation indicators in the overall evaluation,making the evaluation results more scientific and reasonable.It can provide a reference for the evaluation of water quality in polluted areas.
