华北平原地下水人工补给模式研究

Study on Groundwater Artificial Recharge Model in the North China Plain

地下水人工补给是防止地下水资源持续匮乏、维护地下水系统活力的重要举措。在华北地区,按照水文地质条件、补给水源条件、地下水环境问题等的不同,组合筛选出五大代表性区域:山前浅层超采区、中东部平原深层超采区、山东半岛滨海海水入侵区、农业灌溉区和城市地区。针对不同区域,分别阐述了储水空间条件、补给水源条件及实施人工补给的首要目的,归纳出九类人工补给模式,分析了不同补给模式下的补给水源与补给方式。为区域地下水人工补给模式的选择提供依据。

Artificial recharge of groundwater resources is an important measure to prevent the continued lack of groundwater resources and maintain the vitality of groundwater systems.In North China,according to the different of hydrogeology conditions,water supply conditions and groundwater environment problems,five representative areas are selected by combination.They are the shallow overdraft area,the deep overdraft area in the eastern plains,the seawater intrusion in coastal areas of Shandong peninsula,agricultural irrigation areas and urban areas.For each region,storage space,water supply conditions and the primary objective of the implementation of artificial recharge are elaborated.To summarize,there are nine categories of artificial recharge.According to every category,the recharge water resources and recharge mode are analyzed.Artificial recharge mode for the region can be provided the basis for selection.
