| 1. | 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 % 。 |
