在查明盐城市地下水各含水岩组的水文地质特征、开采现状和水位动态的基础上 ,运用数值法对盐城市地下水资源进行评价 ;核定了全市市、县 (市 )、乡 (镇 )三级行政区域地下水可开采量 ,其中Ⅱ ,Ⅲ ,Ⅳ承压含水层可开采量分别为 4992万m3 /a ,6 10 3万m3 /a ,5 478万m3 /a .最后制定了全市地下水合理开发利用规划 ,调减开采区面积 16 33km2 ,控制开采区面积 2 34 8km2 ,扩大开采区面积110 83km2 .
On the basis of ascertaining the hydrogeological features, current exploitation status and water level dynamics of each groundwater aquifer group in Yancheng City, the numerical method was used to evaluate the groundwater resources in Yancheng City. The municipal, county (city), township (town) Grade II, Grade III and Grade IV aquifers can be exploited at 49.92 million m3 / a, 61.03 million m3 / a and 54.78 million m3 / a respectively. Finally, the city’s groundwater rationality Development and utilization planning, reduce the mining area of 16 33km2, control the mining area of 2 34 8km2, expand the mining area of 110 83km2.
