黄河下游悬河段傍河开采地下水的试验研究——以郑州市区黄河滩地为例

黄河下游频频出现的断流现象给沿岸城市的供水造成严重威胁 ,本文根据近年在郑州市北郊黄河滩地供水水文地质勘探中 ,几组大型抽水试验所获得的地质信息 ,论证了傍河地带的地下水资源潜力 ;细颗粒含水地层中的成井技术 ;傍河开采地下水可能诱发的水环境和地质环境问题。文章的结论是 :黄河下游沿岸地带 ,地下水资源十分丰富 ,大规模开采傍河地带的地下水所诱发的环境负效应十分有限 ,具有建立傍河地下水源地的优越条件。

Experimental Study on River-side Groundwater Mining in Downstream Section of Yellow River as An Example of the Bottomland of Yellow River in Shengzhou

The water drying up occurred frequently in the downstream of Yellow River which severely threatened the safety of water supply for cities along the river.Based on several large-scale groundwater pumping tests that conducted in the recent hydrogeologic exploration in the north suburb of Zhengzhou city,the potential of groundwater resources alone the river sides,the construction technique for the water wells in the aquifer with fine grain sand and the possible geologic environmental problems induced by the water mining are evaluated.The results show that the groundwater is very rich along the downstream of Yellow River and that the environmental side effects caused by heavily groundwater mining in the riversides are not serious.So it has advanced conditions to set sites for groundwater mining in the riversides.
