海河流域东南段地下水系统调蓄潜力大,调蓄能力强,由于调蓄水源欠缺,地下水的人工调蓄研究停滞不前。研究区近年修建的大量平原水库,为地下水的人工调蓄提供了水源条件。由于单纯依靠平原水库调蓄地表水,不仅侵占大量农田,还将产生诸如水资源浪费、土壤次生盐渍化等环境地质问题。利用地下水巨大的调蓄空间和有利的调蓄途径,凭借一定的回灌工程,将平原水库蓄存的地表水回灌至地下蓄存,同时解决了地下水调蓄的水源问题和地表水调蓄空间、蒸发及其他环境地质问题,是水资源可持续利用的有效途径之一。 The groundwater system in the southeastern part of the Haihe River Basin has great potential for regulation and storage and good regulation and storage capacity. Due to the lack of regulation and storage of water resources, the manual regulation of groundwater has been stagnating. A large number of plain reservoirs constructed in recent years in the study area have provided water conditions for the manual regulation of groundwater. Due to the pure reliance on the plain reservoirs for surface water storage, it not only invades a large amount of farmland, but also causes environmental and geological problems such as waste of water resources and soil secondary salinization. Taking advantage of the huge storage space of groundwater and the favorable storage and retrieval methods, the recharge of surface water in the plain reservoirs can be recharged to underground storage by virtue of a certain recharge project. At the same time, the problems of groundwater storage and storage and surface water storage are solved Space, evaporation and other environmental and geological issues are one of the most effective ways for the sustainable use of water resources.
