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.
