摘要：

The objective of the research is to evaluate spatial groundwater quality based on improved fuzzy comprehensive assessment model with entropy weights (FCAEW) in geographical information system (GIS) environment. This paper explores the method of comprehensive evaluation of groundwater and sets up an evaluation model applying GIS and FCAEW. Groundwater samples were collected and analyzed from 29 wells in Zhenping County, China. Six parameters were chosen including chloride, sulfate, total hardness, nitrate, fluoride and color. Better spatial interpolation methods for evaluated parameters are found out and selected according to the minimum cross-validation errors from the interpolation methods. FCAEW model was carried out with the help of GIS which makes the evaluating process simpler and easier and more automatically, effectively, efficiently and intelligently. The result embodies the feasibility and effectiveness of FCAEW in GIS when compared with other comprehensive evaluation methods.
