摘要
地下水污染防控区划对地下水保护、污染有效防治和管理有着重要的意义.以北京市平原区为背景建立了以污染风险评价、地下水价值和地下水源保护区三者叠加分析的地下水污染防控区划,为了得到更准确的地下水污染防控区划,本研究对其进行了不确定性分析.通过改变毒性、迁移性和降解性的权重值和地下水污染风险、地下水价值和地下水源保护区的权重值对其进行敏感性分析,研究结果表明,地下水污染风险、地下水价值和地下水源保护区的权重值比毒性、迁移性和降解性的权重值更为敏感.
Groundwater pollution prevention mapping has important meaning to groundwater protection,pollution prevention and effective management.A mapping method was built through combining groundwater pollution risk assessment,groundwater value and wellhead protection area zoning.To make the method more accurate,two series of uncertainty analysis were performed and discussed.One was performed by changing the weights of the toxicity,mobility and degradation of pollutants,and the other was by changing the weights of groundwater pollution risk,groundwater value and wellhead protection area zoning.The results showed that the weights of groundwater pollution risk,groundwater value and wellhead protection area zoning were more sensitive than the weights of toxicity,mobility and degradation of pollutants.
