摘　　要：本文通过系统分析郑汴新区水文地质条件,采用DRASTIC法,选取地下水位埋深、净补给量、含水层介质类型、土壤介质类型、地形坡度、包气带介质类型和含水层渗透系数共七项影响因子对郑汴新区地下水脆弱性进行了评价。并借助于GIS技术强大的输入、空间分析及制图功能,绘制了地下水环境脆弱性评价分区图。结果表明,郑汴新区地下水最脆弱的地带位于黄河南岸的黄河滩地、背河洼地区,以及中牟—开封南黄河冲积平原区,符合实际情况。地下水环境脆弱性评价图为城市规划、地下水资源开发利用及保护提供水文地质方面的依据。Based on the systemically analyze of the hydrogeology conditions of Zhengzhou-Kaifeng District, the vulnerability of the ground water is evaluated by DRASTIC method considering seven effect factors, such as the water level, net recharge, aquifer media type, strata, topography, vadose zone media type and the aquifer permeability. The vulnerability evaluation map of groundwater environment is developed using GIS technique which is powerful in function of input, spatial analysis and drawing. The evaluation results show that the vulnerable areas in the Zhengzhou-Kaifeng District appear at the river beach and low-lying land in the south of the Yellow River, and the alluvial plain area from Zhongmou to the southern of Kaifeng which is consistent with the actual situation. The groundwater environment vulnerability evaluation map would provide a hydrology geological basis for the city planning, development, utilization and protection of groundwater resources.
