地下水型饮用水水源补给区划分——以辽宁省沈阳市北部某地区饮用水水源为例

Division of Groundwater Drinking Water Source Recharge Area:Taking A Drinking Water Source in A Region of North Shenyang,Liaoning Province As An Example

选择辽宁省沈阳市北部某地区集中式地下水型饮用水水源作为研究区,收集其地形地貌、水源所属地下水含水系统的地质和水文地质概况等相关信息进行分析。选择公式法,根据含水层岩性,采取经验值参数,以水源开采井保护区外为基准,以15 a(5475 d)为地下水质点迁移时间,计算得出补给区面积为40.18 km^(2)。鉴于补给区边界部分横跨村庄,在补给区定界过程中,将横跨村庄纳入补给区范围内,切实加强补给区安全防护。并从补给区环境管理方面提出对策和建议。

A centralized groundwater drinking water source in a region of north Shenyang,Liaoning province was selected as the research area,and relevant information such as landform,geology and hydrogeology of the groundwater water-bearing system to which the source belongs was collected for analysis.According to the lithology of the aquifer,the area of the recharge area was 40.18 km^(2)by applying the formula method,using the empirical value parameters,taking the outside of the water source exploitation well protection area as the benchmark and taking 15 a(5475 d)as the migration time of groundwater mass points.In view of the fact that part of the boundary of the supply zone spanned the villages,in the process of demarcating the supply zone,the villages across the supply zone would be included in the scope of the supply zone,and the security protection of the supply zone would be effectively strengthened.Countermeasures and suggestions from the environmental management of the recharge area were put forward.
