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 ob-tained 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.
