摘　　要：基于福州市地质和水文地质条件,采用DRASTIC模型对福州市地下水脆弱性进行评价。利用ArcGIS软件分别形成7个参数的空间分布,根据每个指标因子权重进行叠加分析,获得地下水脆弱性指数,从而对福州市地下水脆弱性分级分区。结果表明福州平原、长乐平原及福清江阴沿海一带风积平原的地下水脆弱性高;沿海海积平原的脆弱性中等-较高;中西部低山丘陵的脆弱性低。The DRASTIC model was used to evaluate the vulnerability of groundwater based on the geological and hydrogeological conditions of Fuzhou City.ArcGIS software was applied to form a spatial distribution of seven parameters.Groundwater vulnerability indexes are obtained by weighted superposition of various indicators,as a result,the groundwater vulnerability zones in Fuzhou City are delimited.The results indicate that the groundwater vulnerability in Fuzhou Plain,Changle Plain and the coastal areas of Jiangyin is high;the groundwater vulnerability of coastal marine plains is medium to high;The groundwater vulnerability of hills in the central and western regions is low.
