摘要
以徐州市城区地下水系统为研究对象,考虑了含水层埋深,含水层补给,含水层介质类型,土壤介质类型,坡度,包气带厚度和渗透系数七项评价因子,采用Drastic方法对该市地下水系统脆弱性进行了风险评价。结果表明,研究区内地下水脆弱性较高且分布不均。利用脆弱性等级划分实现了徐州城区地下水脆弱性分区图,以期为后续的监测和治理工作提供科学依据。
Taking the groundwater system of Xuzhou city of Jiangsu Province as an example, the vulnerability risk of groundwater system is assessed by adopting seven factors of Drastic model, including water depth, recharge, aquifer media, soil media, topogra- phy, vadose zone media and conductivity. The results indicate that the groundwater in the area has high vulnerability index and une- ven distribution. In view of vulnerability grades, the groundwater vulnerability mapping is realized to provide scientific basis for the further monitoring and recovery activities.
