摘　　要：松花江地处寒冷地区,每年冰封期长达5个月之久,其环境污染特征与国内其它大江河有着明显的不同。冰封期有机毒物污染加重是松花江最重要的环境污染特征；松花江流域存在着工业企业的点源污染和地表径流带来的面源污染,研究表明,松花江流域的有机毒物污染是以点源污染为主；有机毒物对江水中COD_(Mn)的贡献值极小,甚至不产生贡献。江水中COD_(Mn)值不能反映出有机毒物的污染状况。Songhua River lies in frigid area ,the period of ice sealed lasts for five months every year .Its character of organic pollution is obviously different from other great rivers. The most important character is that organic poison pollution become more serious in period of ice sealed ; The rder the source pollution from industry and Face the source pollution from The earth＇s surface path flow exist in Songhua River valley, The research indicates that organic pollution in Songhua River valley is majority from Order the source pollution;Organic poison contribute less content of CODMn to fiver, even nothing. The content of CODMn in fiver can＇t reflect the condition of the organic poison pollution.

关 键 词：有机污染物 污染特征 冰封期
