河流重金属污染对两侧浅部含水系统影响的作用途径

The way of action of the influences on shallow aquiferous system of both sides of the river polluted by heavy metals

通过理论计算和实际试验,研究和分析了河流中重金属元素的地球化学行为及其对两侧浅部含水系统的影响。结果表明,在含水层渗透性能弱的平原河网地区,受重金属污染的河流对两侧浅部含水系统的影响作用,不是直接以水力交替和弥散作用的方式,而是在人为因素的媒介作用下进行的。

The geochemical behaviour of heavy metals in river and its effect on shallow aquiferous system of both sides of the river are studied by theoretic calculation and experiments. It is shown that the effect on shallow aquiferous system of both sides of the river is through the medium of artificial factor rather than with hydraulic alternation and diffusion process in a network of waterways of plain area where the permeability of aquifer is weak.
