郑州市地下水资源评价与地下水库调蓄方案

Assessment of Groundwater Resources and Underground Reservior in Zhengzhou City

目前郑州市城市供水量约６０％ 来自黄河．但自１９７１ 年以来，黄河下游多次出现断流现象，１９９２ 年以来黄河郑州段脱流、断流现象频繁出现，并有愈演愈烈之势．这对于主要依靠黄河作为供水水源的郑州市构成了巨大的潜在威胁．因此，科学地评价地下水资源，合理地开发利用地下水，对郑州市社会、经济和环境的可持续发展，具有特别重要的实际意义．本项研究在水均衡法评价地下水资源的基础上，采用数值方法评价了郑州市地下水资源。

In Zhengzhou City,about 60 per cent of municiple water supply comes from Yellow River. The Yellow River downriver cut off has taken place many times since 1971, and Yellow River setting off occurred several times in Zhengzhuo aera since 1992, which is a great latent crisis for Zhengzhuo City. Therefore, rational exploitation and utlization of the groundwater resources is very important to the sustainable development of the society, economics and environment in the Zhengzhou City. This research is based on the groundwater resources assessment with methods of the balance and the numeric,and the scheme of the underground reservior is presented for artificial regulation of the groundwater resources in the studied area.
