永城市城市应急或后备水源地选址

Yongcheng Urban Emergency or Backup Water Source Site Selection

永城市地处黄淮河冲积平原,地表水系发育,但地表水资源不丰富,地表水做为供水水源的能力十分有限。浅层、中深层地下水为工农业生产、城市供水的主要水源。本文分析了永城市浅层、中深层地下水赋存条件及其水文地质特征,对浅层、中深层地下水资源量进行计算评价,提出了城市后备水源地取水目的层及选址建议。

Yongcheng City is located in the alluvial plain of huanghuai river,where the surface water system is developed.However,surface water resources are not abundant,and the capacity of surface water as the water supply source is very limited.The shallow and middle deep groundwater is the main water source for industrial and agricultural production and urban water supply.The conditions of occurrence and hydrogeological characteristics of shallow and middle and deep groundwater in Yongcheng City are analyzed.This paper puts forward some suggestions on the target layer and site selection of water intake from backup water sources.
