Assessment of Groundwater Vulnerability in Fuzhou City Based on ArcGIS and DRASTIC Model
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.
