摘要
基于地下水饮用水源地与污染源相互作用的机理,综合考虑污染源荷载风险(L)、地下水污染风险(V)和地下水饮用水源地属性(P),建立了一套地下水饮用水源地污染源风险等级评价指标体系;运用层次分析法确定了风险等级评价指标体系中21个指标的权重,并通过加权求和模型,构建了污染源风险等级评价指数(I)的计算方法;依据污染源风险等级评价指数将污染源风险等级划分为高风险、较高风险、中等风险和低风险四个等级,以为地下水饮用水源地供水安全保障提供科学依据。
Based on the interaction mechanism between the drinking groundwater wellhead and the contamination sources,this paper develops a risk level evaluation system of contamination sources, combining the load risk of contamination source (L) ,the pollution risk of groundwater (V) and the property of drinking groundwater wellhead (P). Then it determines the weights of the twenty-one indicators of the evaluation system by analytic hierarchy process method, and obtains the values (I) of the risk level evaluation of con- tamination sources by the weight-adding model. At last,the paper divides the values (I) of the risk level e valuation of contamination sources into four kinds, highest level, higher level, medium level and low level, which can provide scientific evidence for the water supply security of drinking groundwater wellhead.
