基于GSAHV模型的傍河地下水水源地脆弱性评价

Groundwater Sources Vulnerability Assessment Based on GSAHV Method

分析傍河地下水水源地地下水环境脆弱性的主要影响因素,建立了GSAHV脆弱性评价模型。将5个不同评价指标分成5级,利用改进的集对分析方法确定地下水的脆弱性等级。该模型在进行地下水源地脆弱性评价时,综合考虑了水量、水质和生态环境三方面因素。与传统的评价方法相比,将污染物的来源从降水入渗方式转为与地下水联系更为密切的地表水体,而且加入了地下水可开采资源量和生态环境影响等重要指标。新的评价体系是对传统方法的改进,更加适合傍河地下水水源地的脆弱性评价。

An evaluation system for groundwater sources vulnerability assessment is established in this paper, in which every factor is divided into five levels. The evaluation result is determined by set pair analysis method. In contrast to the previous methods, it covers groundwater exploitation amount and ecological environment factors. It is more suitable for groundwater sources vulnerability assessment.
