Fuzzy optimization assessment of DRASTIC groundwater vulnerability based on entropy weight and GIS
Groundwater vulnerability assessment and mapping are the basic work for groundwater environment protection. DRASTIC index system is the most popular in the world. The entropy weight Fuzzy optimization method was introduced to groundwater vulnerability assessment coupled with GIS in this paper. It avoids the influence of human factor when the parameters weight is evaluated. Take Huangshuihe river catchment as an example, the entropy weight of DRASTIC parameters and the optimal degree of overlay area were calculated. Thus, the groundwater vulnerability of Huangshuihe river catchment was divided 3 grades: high, medium and low. A good effect of the application is obtained.
