摘要
在南水北调进京前,平谷平原区属于地下水超采区."南水"进京后,为了加快恢复平谷区地下水资源储量,在分析区域水文地质条件、地下水动态及可利用回补水源等基础上,制订了2种地下水调蓄方案,并利用数值模拟技术预测了不同方案的实施效果.结果表明:若不实行地下水人工回补,仅靠地下水减采,地下水位亦可逐步恢复;若地下水减采的同时,在泃河、洳河上游实行人工回补,地下水位恢复效果更加显著.研究成果为指导平谷区地下水资源储量增加、促进区域水资源可持续利用服务.
Abstract
Before the implication of South-to-North water transfer project supplied water to Beijing,the Pinggu plain suffered from groundwater overexploitation.To address this issue and increase groundwater storage,two groundwater storage schemes were devised.These schemes were evaluated using numerical sim-ulation technology,considering regional hydrogeological conditions,groundwater dynamics,and available recharge water sources.The findings indicated that solely reducing groundwater extraction could gradually restore groundwater levels.However,implementing artificial recharge in the upper reaches of the river alongside reduced extraction yields a more significant groundwater level recovery effect.This research out-comes will provide guidance for enhancing groundwater resource reserves and promoting the sustainable uti-lization of regional water resources in Pinggu.
