华北平原地下咸水区水资源短缺，深层地下水严重超采，生态环境恶化。开发利用该区地下咸水可增加地下水库库容，减少潜水蒸发和雨水径流，增加降雨入渗。在时间和空间上分布不均匀的自然降雨可以转化为可用的水资源。总结了利用微咸水灌溉农村的经验，既可抗旱增产，又可调节地下水位。增加雨水对地下水的补给，改善地下水水质。提出了城市雨水控制与利用的方法。
The saline groundwater region of North China Plain is short of water resources, the deep groundwater has been overdrawn seriously and the eco - environment has deteriorated. Exploiting and utilizing the saline groundwater in this region can increase the underground reservoir capacity, reduce the evaporation of phreatic water and runoff of rainwater, and increase the rainfall infiltration. Natural rainfall that is unevenly distributed in time and space can be transformed into available water resources. This paper summarized the experience of using brackish water for irrigation in rural area, that can not only combat drought and increase crop yields, but also regulate groundwater table level. Increasing groundwater recharge by rainwater and improve groundwater quality. The authors also recommend methodologies for the control and utilization of rainwater in urban area.
