| 摘 要： | 松花江水质污染严重,但其水质净化作用也很强,两者相互作用结果使哈尔滨江段上游断面江水基本符合地面二级水标准,下游断面基本符合地面三级水标准,把通过河底沉积物向漏斗渗透补给的江水中的污染质,大部分净化在含水层之外,对优质地下水起到了保护作用。

| Abstract: | The Songhua River is seriously polluted but its purificition (dilution, absorption, filtering) is also great. The interaction between them makes the water quality meet them standard of the second-grade surface water in the upper stream of Haerbin reaches and that of the third-grade in the lower stream. River bed sediments, through which the river water flows to recharge the groundwater purify most of the pollutants in the river water and keep them out of the aquifers, proteet effectively the good groundwater from pollution. |
