基于模糊集理论的地下水污染综合评价改进体系
|
摘要
基于模糊集理论构建地下水污染综合评价体系五级隶属函数模型,并结合德尔菲法和双权重法建立综合重金属污染物和有机污染物的权重模型。通过实际案例分析,对比现在流行的简单对比评价方法,分析基于模糊集理论的地下水污染综合评价改进体系的特点和优势。本文提出的改进模型主要适用于各个参评因素超标情况接近且不存在单因素否决,可以体现不同参评因子对地下水环境质量的综合影响的评价项目。
This paper introduces a modified evaluation system of comprehensive groundwater pollution based on fuzzy mathematical models. This evaluation system builds a five-degree membership function and a comprehensive weight function by combining Delphi method with double weight method. Using a typical engineering project, this study analysed the features of the modified evaluation system and its advantages over the popular simple comparison method. It found that the weighted average model is applicable in a situation where the contents of every evaluation factor are even and the objective of the evaluation is to externalize the contribution of every evaluation factor to groundwater environmental quality.
