In order to control the land subsidence , adjusting three dimensional exploitive positions and moderately utilizing the leakage recharge from its upper shallow groundwater play a key role in realizing the sustainable development of deep groundwater resources in this area 在控制地面沉降的条件下,深层地下水持续利用的对策是调整开采三维布局,适度开发利用浅层地下水对深层地下水的越流补给。
On the basis of the monitoring results of land subsidence and calculation of deep groundwater resources by using water balance method , it is shown that the leakage recharge from its upper shallow groundwater account for approximately 38 . 2 % , drainage of the clay layers , about 41 . 3 % , water release from the aquifers , around 5 . 6 % and lateral inflow , some 14 . 9 % , of the total groundwater resources 摘要根据天津平原地面沉降监测结果,采用水量均衡法,计算出深层地下水开采量中,浅层地下水越流补给量占38 . 2 % ,粘土性压密释水量占41 . 3 % ,弹性释水量占5 . 6 % ,侧向流入量占14 . 9 % 。
