摘要： 用权重系数概念确定图们江水系陆源污染物进入日本海的主要污染类型和污染因子,得出它属于以有机污染综合指标COD为主要污染因子的有机污染类型。淡水分数判断图们江河口不受潮周循环影响。用零维模型计算其年入海通量为9.055万吨。用排放系数法预测目标年2000和2010年城市污水和工业废水的COD排放量并计算其年入海通量分别为:17.64万吨和45.86万吨.

Abstract: In this paper, primary pollution factor and pollution type of the Tumen River in Northeast China are discribed by weighting coefficient method. The results indicate that the river is organic pollution type and primary pollution factor is CODMn. Based on the correlation between CODMn and BOD5 a simple linear regression equation is obtained. The correlation coefficient is 0.9614. CODMn concentration of interface between river and sea calculated by zero dimension model is 12.61 (mg/l). The annual flux of land based sources COD from the Tumen River system into the Japan Sea is 90.55 thousand tons (1993). Regard 1993 as basic year, the annual flux of the objective years, 2000 and 2010, are forcasted by emission coefficient method. The results are 176.4 and 458.6 thousand tons respectively.
