| 摘 要： | 鉴于松花江流域地下水的重要性和当前污染,运用改进的DRASTIC模型,对松花江佳木斯段5～10 km范围内潜水进行了脆弱性评价。选取净补给量、包气带介质、含水层厚度、地下水水位埋深、土地利用类型、污染源影响和地下水开采模数建成评价指标体系;采用层次分析法确定各指标权重,结合GIS技术实现了脆弱性分区,并将结果与地下水质评价结果进行对比;最后通过敏感度分析讨论了所选指标的合理性。结果表明:地下水脆弱性相对较低和低脆弱区共占研究区面积的82.76%;较高和高的区域仅占8.13%,主要分布在七水厂、江北水源地以及污染强度较大的点源污染周围。地下水埋深、包气带岩性和地下水开采模数是对潜水脆弱性影响最大的因素。评价结果比较真实地反映了松花江佳木斯段潜水脆弱性状况,对城市规划建设和地下水资源的可持续利用具有指导意义。

| Abstract: | Due to the importance and current contamination of the groundwater in the area of Songhua River,phreatic vulnerability assessment was conducted using the improved DRASTIC model at 5-10 km long Jiamusi section.Net recharge,vadose zone material,aquifer thickness,water depth,land use,impact of pollutants and module of groundwater yield were chosen to set up the assessment system.It was combined with GIS to obtain a vulnerability map,which was confirmed by the groundwater quality.Moreover,the rationality of the... |
