傍河区域地下水脆弱性研究——以第二松花江流域为例

 地下水脆弱性研究是合理开发利用和保护地下水的基础,它一直是国际水文地质研究的热点问题之一。以第二松花江流域地下水为研究对象,分别采用DRASTIC 方法和GOD 方法对地下水环境脆弱性进行评价,并利用实测铬含量对评价结果进行验证对比。研究结果表明:DRASTIC 模型对第二松花江流域地下水环境脆弱性的评价较为合适,评价结果更能真实地反映研究区地下水脆弱情况;第二松花江流域傍河区域的地下水环境较为脆弱,容易受到污染,故在布设水源地开采井时应尽量避开地下水高脆弱区,做到合理有效地开发利用地下水资源。

Groundwater vulnerability to contamination near the river:A case study of the second Songhua River

The groundwater vulnerability is a basic issue for the groundwater to be protected and used reasonably, so it is one of the hot topics in the hydrogeology field. The DRASTIC method and the GOD method are used to assess the groundwater vulnerability of the second Songhua River basin, and then the assessment is evaluated by using the measured values of Cr. The results show that the DRASTIC method is better, and it could reflect realistically the vulnerability of the researched area. The groundwater environment near a river is vulnerable and easy to be polluted. In order to take advantage of the groundwater resources effectively, the well of the water source should be constructed far away from the high-risk areas.
