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。
According to the geological information obtained from several large-scale pumping tests in the hydrogeological exploration of the Yellow River beach in the northern suburbs of Zhengzhou City in recent years, this paper argues that the cut-off phenomenon in the downstream of the Yellow River poses a serious threat to the water supply in the coastal cities. Potential of groundwater resources; well-formation technology in fine-grained aquifer; water environment and geo-environmental problems that may be induced by groundwater exploitation near the river. The article concludes that the groundwater resources in the coastal area of the lower Yellow River are very rich, and the negative environmental effects caused by the groundwater exploitation along the large-scale exploitation of the riverbanks are very limited. They have the advantages of establishing underground water sources in the riverside.
