摘　　要：通过一年时间对黄浦江上游水进行有机物分子量分布的测定 ,表明黄浦江有机物分子量分布的变化受湖泊水质和排入污水的共同影响 ,其主要特征是溶解性的低分子量有机物占多数 .黄浦江水中的腐殖酸含量和三氯甲烷生成潜能在夏季时最高 。The distribution of molecular weight(MW)of dissolved organics in Huangpu River source has been determined for one year. The result demonstrated that change in the distribution of MW in Huangpu River was influenced by both lake water quality and wastewater discharged and was characterized by low MW of dissolved organics accounting for great majority. The concentration of humic substances and trihalomethane formation potential(THMFP)were high in summer and low in winter.
