北方城市地下水应急供水水源地评价指标体系研究

Indicator system for emergency groundwater supply target-area evaluation in northern chinese cities

结合我国北方城市区域水文地质背景以及区域地下水开发利用现状,对照城市应急供水的地下水资源属性、应急供水属性、水源地建设条件以及环境影响4个属性指标层的内涵,利用层次分析模型,建立了北方城市地下水应急供水水源地的综合评价指标体系。并以石家庄市为例,开展了石家庄市地下水应急供水水源地适宜性评价,对所选取的评价指标体系进行了验证,结果显示,所建立的评价指标体系能够在宏观上反映区域地下水的丰富程度,对于开展地下水应急供水、确定北方城市应急供水水源地及实施城市应急供水、水源工程建设具有一定的指导意义。

The indicator system for emergency groundwater supply target - area＇ evaluation in northern chinese cities was proposed in this paper based on Analytical Hierarchy Process, and the groundwater resources attributes, aquifer characteristics for emergency water supply, construction requirements as well as environmental problems were taken into account in this system according to the understanding of the regional hydrogeology background and groundwater utilization in northern China. The case study in Shijiazhuang city showed that indicator system formed can be used to map the suitable area for future emergency groundwater supply objectively and it has a guiding significance for future emergency groundwater supply target - area allocation and construction.
