大连市旅顺地区地下水的水质恶化及其对策

Deterioration of underground water quality in Lushun district and its countermeasures

根据旅顺口区地质结构和地下水体系分布 ,依据旅顺口区地下水监测结果 ,分析评价了旅顺口区地下水的水质现状。局部地区地下水位大幅度下降 ,引起海水倒灌 ,淡水遭到严重污染。有些地区地下水虽未发生海水倒灌 ,但氯离子含量已明显增高 ,水质也逐趋恶化。针对存在的问题 。

We test and monitor the underground water in Lushun district according to the geological structure and the underground water distribution. It reveals that there is, in some region, serious pollution or decreasing in underground water level, resulting sea-water backward pouring. Countermeasures to cope with this deterioration trend are proposed.
