摘　　要：在分析商丘市规划中心城区自然地理及水文地质条件的基础上,基于DRASTIC评价方法,本文选取地下水位埋深、含水层岩性、土壤类型、地形坡度、包气带介质类型和含水层富水性6项指标作为评价因子,建立优化改进的评价模型—DASTIY模型,运用层次分析法(AHP)确定权重,并借助MapGIS进行研究区浅层地下水防污性能评价和分区。结果表明,商丘市规划中心城区浅层地下水防污性能整体为差,评价结果可为地方政府制定地下水资源保护及产业布局提供决策依据。Based on the natural geography and hydrogeology conditions of Shangqiu City Planning Central City Zone and DRASTIC method,six evaluating indicators such as the groundwater depth,aquifer lithology,soil type,topography,vadose zone media type and water yield property were choosed to build an improved evaluation model-DASTIY model,of which the weight was determined by using the analytic hierarchy process( AHP),and MapGIS was used to evaluate and partition the groundwater antipollution capacity in this study area.The result showed that the shallow groundwater had poor groundwater antipollution capacity in this study area,which can provide decision-making basis for local governments to formulate plan for groundwater resource protection and industrial layout.
