Division of Groundwater Drinking Water Source Recharge Area:Taking A Drinking Water Source in A Region of North Shenyang,Liaoning Province As An Example
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 km2 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(5 475 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.
