With the Harbin reach of Songhua River as the studied object, the EFDC water quality dynamic model is developed, the main pollutant parameters COD, NH3-N, combined with pollution load scenario analysis method for quantitative evaluation of the Harbin reach of the Songhua River and its tributary estuary sections under the change of water quality. The results show that the outlet COD concentration of Dadingzi Hill section meets the quality requirements of category Ⅲ and below, the Ashe estuary and Hulan estuary concentration in the dry season, flood peach, normal water period and high water period respectively, the maximum values are not more than 29.3, 22.3, 41.82, 32.13 mg/L, and 47.75, 36.27, 65.4, 41.47mg/L of Dadingzi Hill eatuary section in dry season in the category Ⅲ then, highest concentration of NH3-N was 8.73 and 2.92mg/L at Ashe and Hulan estuary sections, which in flood peach period still remain in the category Ⅱ, with the two highest is 6.3 and 2.23mg/L respectively, in dry season, while the Dadingzi Hill estuary section is kept at category I, the Ashe and the Hulan estuaries can not exceed 7.57 and 1.79mg/L respectively.
