摘    要:为促进地下水水资源保护和利用,根据研究区域的特点以及地下水防污性能的影响因素,基于DRASTIC模型,选用以下6个因子:地下水水位埋深、降雨入渗补给量、表层土壤类型、包气带岩性、含水水力传导度以及土地利用类型建立了再生水灌区地下水特殊防污性能区划模型。采用地理信息系统GIS技术和内梅罗指数法,绘制研究区域地下水综合污染指数分布空间图,并且探讨了防污性能区划的验证方法以及等级划分标准。结果表明:地下水综合污染指数与研究区域的防污性能具有很好的相关性(R2=0.9591),采用DRASTIC模型评价地下水特殊防污性能是可行的,可为再生水灌区地下水的保护以及利用规划提供重要借鉴。

关 键 词:地下水,验证,模型,再生水灌区,防污性能

Abstract:In order to protect and utilize groundwater resource, the groundwater special vulnerability zoning model for the reclaimed water irrigation district was established which was based on DRASTIC model. The six factors were considered which were the groundwater depth, rainfall recharge, surface soil media type, unsaturated zone lithology, hydraulic conductivity of aquifer and land use type in this model according to the actual conditions of study area and influencing factors of groundwater vulnerability. By the GIS technology and Nemerow index, the groundwater comprehensive pollution index distributing map was maken, and the verification method and classification standards of the groundwater vulnerability zoning were explored. The results indicated that there was a significant regression relationship between groundwater comprehensive pollution index and groundwater vulnerability in research area (R2=0.9591). The groundwater vulnerability assessment result by the DRASTIC model was reasonable. This result can be used for the planning of the groundwater protection and utilization in reclaimed water irrigation districts.
Keywords:groundwater  verification  models  reclaimed water irrigation district  vulnerability
