常熟地区浅层地下水脆弱性评价研究

Study on Vulnerability Assessment of Shallow Groundwater in Changshu Area

《地下水条例》自2021年12月1日发布以来,地下水污染防治越来越受到重视,对极易受污染的浅层地下水进行脆弱性研究就显得尤为重要。本研究利用ArcGIS综合数据分析能力建立DRASTIC模型,对常熟地区浅层地下水的地下水位埋深等7个模型评价因子进行了分析评价,最终完成了常熟地区浅层地下水脆弱性评价,评价结果体现了常熟地区浅层地下水总体脆弱性较高的现状。

Since the promulgation of the groundwater regulations on December 1,2021,the prevention and control of groundwater pollution has been paid more and more attention.It is particularly important to evaluate the vulnerability of shallow groundwater,which is highly vulnerable to human pollution.Using the comprehensive data analysis ability of ArcGIS,a drastic model is established to analyze and evaluate seven model evaluation factors such as the groundwater table depth of shallow groundwater in Changshu area.Finally,the vulnerability evaluation of shallow groundwater in Changshu area is completed.The evaluation results reflect the current situation of high overall vulnerability of shallow groundwater in Changshu area.
