基于模糊综合评价法的地下水质量评价——以海河流域某电厂厂址区域为例

Evaluation of Groundwater Quality Based on Fuzzy Comprehensive Evaluation Method,Taking the Site of a Power Plant in Haihe River Basin as an Example

选取海河流域某燃煤发电厂厂址所在区域的地下水为观测样本,调查获取影响该区域地下水质量的8种主要因素的指标值。通过引入模糊综合评价法,以8种因素作为评价因子,构建地下水质量模糊综合评价模型,最后通过Matlab编程计算各级指标值,对该区域地下水环境质量进行评价分级,为今后建设项目的地下水环境影响预测和评价提供理论依据。

Groundwater samples from the location of a coal-fired power plant in Haihe River Basin are selected as observa- tion samples. The index values of 8 main factors affecting the quality of groundwater in the area were investigated.Through the introduction of fuzzy comprehensive evaluation method, taking 8 factors as evaluation factors, construction of fuzzy comprehensive evaluation model for groundwater quality. At last, the index values at all levels are calculated by MATLAB programming, evaluation and classification of groundwater environmental quality in this area, it will provide theoretical basis for prediction and evaluation of groundwater environmental impact in future projects.
