中文摘要:

本文结合海河流域地下水环境的具体情况,分别构建了地下水资源量评价指标体系和水质评价指标体系,并将其应用于天津、沧州、衡水、石家庄和唐山五个典型区域的地下水环境风险评价中,结果表明石家庄地区水质优良,地下水储存量较丰富;天津及唐山地区水质尚可,水资源存储量较差;沧州和衡水地区地下水质劣于一般程度,存储量较差,且超采现象很严重。这与相关资料显示的各区域地下水系统实际环境情况基本吻合,验证了所建立指标体系选取的合理性,可为其它区域的地下水环境质量综合评价提供参考。

英文摘要:

In this paper, the index system of groundwater to the characteristics of groundwater environment in of groundwater environment risk in typical areas quality and quantity were established respectively according Haihe basin. And then they were applied to the assessment--Tianjin, Cangzhou, Hengshui, Shijiazhuang and Tangshan. The results showed that groundwater quality was excellent, water quantity was abundant in Shijiazhuang; groundwater quality was fairish, water quantity was of a sort in Tianjin and Tangshan; both groundwater quality and quantity were in a worse condition in Cangzhou and Hengshui. This was consistent with the real environmental situation of groundwater system shown by relevant materials basically, which proved rationality of the index system, and offered reference for comprehensive assessment of groundwater environmental risk in other areas.
