%X 淮河流域新型工业化、城镇化及农业现代化近年来高速发展&#65292;可能引发区域地下水生态环境问题&#65292;因此选取流域内的信阳市淮滨县为研究对象&#65292;在系统分析研究区水文地质条件的基础上&#65292;按照研究区实际情况&#65292;选取7个主要影响因素作为评价因子&#65292;利用ArcGIS对各评价因子进行加权叠加分析&#65292;应用DRASTIC评价模型对工作区进行地下水脆弱性评价。评价结果表明研究区内大部分地区的地下水脆弱性为较高等级&#65292;脆弱性等级为中等的地区主要为淮河以南的张庄乡一带以及王店乡的北部地区&#65292;淮滨县城区的东北部局部地区&#65292;王店乡以及期思镇的南部白露河沿线为脆弱性高等分区。<br>The rapid development of new industrialization, urbanization and agricultural modernization in the Huaihe River Basin in recent years may lead to regional groundwater ecological and environmental problems, therefore, Huaibin County of Xinyang City in the basin was selected as the research object, and on the basis of systematic analysis of the hydrogeological conditions of the study area, seven main influencing factors were selected as evaluation factors according to the actual situation of the study area, and the weighted superimposition of the evaluation factors was carried out by using ArcGIS. ArcGIS was used to analyze the weighted superposition of the evaluation factors, and the DRASTIC evaluation model was applied to evaluate the vulnerability of groundwater in the working area. The evaluation results show that the vulnerability of groundwater in most areas of the study area is high, and the areas with medium vulnerability are Zhangzhuang Township and the northern part of Wangdian Township south of Huaihe River, the northeastern part of urban area of Huaibin County, and the area along Bailu River in Wangdian Township and the southern part of Qisi Township are the high-vulnerability sub-areas.
