黄河三角洲南部冲洪积扇区地下淡水调蓄条件研究

Study on Underground Fresh Water Storage in Southern Flood Alluvial Area in the Yellow River Delta Area

摘要:

黄河三角洲南部冲洪积扇区浅层地下水由于长期大量开发利用，早已形成了区域性漏斗群。通过对漏斗区地下水赋存条件和调蓄条件的分析，提出了由新建的引黄主干渠引黄河水，采用河渠、坑塘内施工回灌引渗，以及丰水期大气降水地表径流拦蓄引渗和引黄河水引渗回灌联合调度的方案，并从调蓄资源增量、调蓄可行性和调蓄效益等方面进行了论证。

Abstract:

Due to development and utilization of shallow underground water in southern flood alluvial area in the Yellow River Delta area, regional group of funnels have been formed in this area. Through analysis on occurrence and storage conditions of underground water in funnel area, some countermeasures for water storage are put forward, such as guiding water from the Yellow River by using new diversion channels, recharging and infiltrating by using construction in chanals and ponds, and realizing storage and infiltration of rainfall or by leading water from the Yellow river in rainy season. Regulation and storage resources, regulation of resource increment, storage feasibility and effectiveness are briefly introduced as well.
