摘要
济南泉域地下水从化学组分时间变化情况看,随着人类活动的增强,水体的总硬度、SO_4^(2-)、Cl^-和NO_3^-等指标均呈上升趋势,且近期和人类活动强作用区离子浓度升高的速度较快;济南泉域和大辛河流域地下水水质的空间变化,亦可以说明人类活动能够影响地下水水质的分布,人类活动强作用区地下水的水质劣于人类活动弱作用区。
According to time variation of groundwater chemical components of Jinan spring region, it showed that the concentration of items such as Total Hardness, SO_4^(2-) , Cl^-, NO_3^- and so on was increased with the enhancement of human activity, and also in human high-activated area and in recent time ionic concentration rose rapidly. This result was further proved by spatial distribution of groundwater quality in Jinan spring region and the Daxin river drainage area, human activity has already impacted great effect on the distribution of groundwater quality, and the water quality in high-activated area was worse than that of low-activated area.
