沉积环境和人类活动对苏锡常地区浅层地下水的水质效应

The effects of sedimentary environment and human activity on shallow groundwater quality in Suxichang area

为指导苏锡常地区浅层地下水科学合理地开发利用,笔者从地质历史的角度分析了沉积环境对浅层地下水水质分布的影响;充分利用研究区域浅层地下水的历史水质资料,分析人类活动影响下的水质演化规律。结果表明:沉积环境对研究区的浅层地下水水质的空间分布特征具有控制作用,而人类活动对浅层地下水的水质演化具有污染和开采淡化的双重效应。

To provide scientific reference for shallow groundwater exploitation, this paper analyzed the effect of sedimentary environment on the distribution of shallow groundwater quality from the angle of geological history and the effect of human activity on groundwater quality evolution and on the basis of sufficient utilization of historical water quality data. The result shows that the sedimentary environment controls the spatial distribution of groundwater quality and the human activity has exerted two kinds of effects on water quality evolution, i.e., contamination and freshening by groundwater exploitation.
