长春市浅层地下水动态监测分析

An Analysis on Dynamic Monitoring of Groundwater in Shallow Layer in Changchun

本文根据长春市浅水层观测井的检测资料,从水位埋深、水温和水质等3个方面对各自变化趋势和原因进行了分析,地下水位埋深值减小,减小原因与限制开采地下水有关;地下水温度上升,水温与气温密切相关,但响应存在滞后;研究区水质不容乐观,而随着浅层地下水位的升高,工农业生产及生活垃圾的堆放等更容易对地下水差生污染,应该得到应有的重视。

On the basis of monitoring data of observation well in shallow layer in Changchun,this paper analyzes the variation trend and its reasons of groundwater level,water temperature and water quality.The groundwater level decreases,it is relevant to restriction exploitation the groundwater;the water temperature increases.The water is closely related to air temperature,but there is response lag;the water quality is not optimistic for the study region.Moreover,the industrial and agricultural production and home scrap will pollute the groundwater with the increase of groundwater level in shallow layer.The problem should be paid attention.
