基于敏感因子指数法的垃圾填埋场地下水污染过程识别技术中权重计算方法优化

Optimization study on weight calculation method based on the sensitive factor index method

敏感因子指数法是一种可对垃圾填埋场地下水污染过程进行识别的有效方法。其中,确定敏感因子在各氧化还原特征区内所占的权重值是整个方法体系中一个重要环节。在前期研究的基础上,本文将几种权重计算方法应用于敏感因子指数法中,并结合实际污染场地得出分区结果。通过对比分析,得出组合权重法能够科学、客观、准确地确定各敏感因子的权重,比较适用于敏感因子指数法。

Sensitive factor index method is a kind of effective method to identify the landfill groundwater pollution process.The value of sensitivefactors weights in various redox characteristic zones is an important part in the whole system.On the basis of the previous research,three kinds of weight calculation methods were applied to the sensitive factor index method,and the results were obtained combined with the actual landfill in this paper.Through comparison and analysis,the result shows that combination weighting method can evaluate the weight of each factor more scientific,objectively and exactly,as well as more suitable for the sensitive factor index method.
