摘要
以河北平原中、东部及滨海地区为例，根据地面沉降量反求深层地下水开采量的构成，确定了由含水层及粘性土压密所释放的水量分别为多年累积开采量的２４．３６％和３６．４５％，并根据水文地质、地下水动态资料的深入分析，推测在未来的地下水开采中，深层地下水可获得来自系统外部的补给量将不大于总开采量的４％，由此获得了深层地下水资源属性及合理评价的新认识。中国法分类号Ｐ６４１．７，Ｐ６４１．
Taking the middle-eastern and coastal area of Hebei Plain as example,the constitutional proportion of deep-lying groundwater exploitation is derived according to the land subsidence data,and the amount of water released from aquifer and clay layer by compression is determined,which occupies 24.36% and 36.45% of total exploitation amount in the past 19a,respectively.Furthermore,based on the analysis of hydrogeological condition and the observation data of groundwater trends,the recharge capacity which the deep-lying groundwater receives from the outside system in the future is predicted to be less than 4% of the total exploitation amount.Thus,the new knowledge about deep-lying groundwater resources property and its reasonable evaluation is aquired.
