摘　　要：应用WASP7.3模型对松花江哈尔滨段水质现状进行了模拟研究,研究的水质指标包括:NH3-N和COD。首先,分别选用2011年阿什河段和2012年呼兰河段实测值与模拟值进行率定及校验,校验结果为NH3-N和COD模拟值的平均相对误差分别为7.41%、4.41%;将WASP模型与单因子水质评价法进行结合研究,分析结果表明,松花江支流阿什河口内河段近3 a的NH3-N、COD超标较严重,为劣V类水质;以2013年为基准,使用WASP模型分别预测了2014年松花江支流阿什河和呼兰河的污水削减量及水环境容量。Simulation study of the status quo of water quality in Harbin section of Songhua River was carried out by use of WASP7. 3 model. Water quality indices in this study include: NH3-N and COD. First of all,the measured values of Ashe River section in 2011 and Hulan River section in 2012 were used to calibrate and check the simulated values. Results show that as for the simulated values the average relative error of NH3-N is 7. 41% and the average relative error of COD is 4. 41%. Combination of WASP model and single-factor water quality assessment indicates: in nearly three years,within the mouth of Ashi River,the tributary of Songhua River,NH3-N and COD exceeded more seriously and the water quality is worse than Grade V. Taking the year 2013 as a benchmark,WASP model was used to predict the decreased amount of sewage and water environmental capacity of Ashe River and Hulan River.
