三江平原是国家重点农业综合开发区,随着该区建设速度加快,开采利用地下水资源的规模也逐年扩大。但是,目前由于这个地区河流大多已受到污染。不仅影响自身的开发利用,而且波及到近河地带地下水的开采。因此,如何减轻或防止河水入渗污染,对这个地区的合理开发有着十分重要的现实意义。该区砂、砂砾石孔隙潜水含水层结构单一,厚度一般100～200

Sanjiang Plain is a national key agricultural development zone. With the rapid construction of this zone, the scale of exploitation and utilization of groundwater resources has also been expanded year by year. However, at present most of the rivers in this area have been polluted. Not only affect its own development and utilization, but also spread to the exploitation of groundwater near the river. Therefore, how to reduce or prevent river water infiltration and pollution is of great practical significance to the rational development of this area. The sand and gravel pore submersion aquifer in this area has a single structure with a thickness of 100-200
