基于GIS的吉林省西部平原区浅层地下水防污性能评价

Assessment of antipollution capacity of shallow groundwater in the plain area of western Jilin province based on GIS

摘要: 文章在DRASTIC指标体系的基础上,结合吉林省西部平原区的实际情况,利用GIS的矢量制图功能生成各单指标图,通过空间叠加分析模块生成评价单元,并利用GIS的属性数据库对吉林省西部平原的浅层地下水防污性能进行了评价,评价结果与区域环境水文地质条件基本吻合。

Abstract: Based on the DRASTIC index system and the actual conditions of the plain area in western Jilin province,the Vector Drawing Function in GIS Software is applied to draw different single index pictures,which form the evaluation cells by the Module of Special Superposition Analysis.The attribute database of GIS is applied to evaluate the antipollution capability of groundwater environment of the plain area in the western Jilin province.The evaluation results are coincident with the hydrogeological conditions of the region.
