Description
Summary:According to the defect of DRASTIC model in antipollution evaluation of phreatic water of Alluvial plain, selecting 8 assessment factors such as groundwater depth, gas zone lithology, aquifer sand layer thickness, aquifer hydraulic conductivity, rainfall supply, mining intensity, groundwater quality and comprehensive river coefficient, the comprehensive index evaluation model based on the bayes was bulit. The model was proposed to be applied to the evaluation of the antipollution of the phreatic water in Tian Town and surrounding areas in Weihe basin. The range number-possibility degree method is applied to calculate the weight of influence factors, then a phreatic water map of antipollution evaluation zone was suggested. The result shows that the calculation by vulnerability evaluation model based on the bayes is more conformed with the actual situations of study area, and the phreatic water map of antipollution performance evaluation zones can provide some important reference for making antipollution measures for the phreatic water of the study area.
