摘要：

根据研究流域特点建立了冰封期水动力水质模型，结合冰封期水位测量的特点，对水位模拟结果进行了修正，分别利用2006和2007年水文监测数据对模型进行了率定和验证，利用模型对2005年松花江硝基苯水污染事件进行模拟。计算结果表明:建立的冰封期水动力水质模型能够很好地适用于该地区，部分断面硝基苯质量浓度峰值的相对误差为5%~13%，峰值出现时间的绝对误差为2~3 h。利用模型预测了上游边界流量增加20%及减少5%对水质的影响，结果表明:流量增加导致污染团峰值提前22 h到达摆渡河断面，硝基苯质量浓度峰值降低了15%，流量减少导致峰值延迟6 h到达摆渡河断面，质量浓度峰值升高了4.6%。

Abstract:

For the freezing period of the Songhua River mainstream, the hydrodynamics and water quality model was built, which was modified depending on the characteristics of hydrological measurement data in icebound season of 2006 and 2007. The simulated result matched the measurement value very well. And then, this model was used to analyze the nitrobenzene pollution accident of Songhua River. Compared with the observed contamination concentration, the error of simulated value is from 5% to 13%, and the peak value appeared after a lag time of more than 2 hours. Finally, for the two cases of mass flux increased by 20% or reduced by 5%, water quality was further investigated. The simulation result shows that the increased flux leads to the peak value of nitrobenzene appearing on the Baidu River section two hours early and reduced by 15%; the reduced flux leads to the peak value of nitrobenzene appearing six hours later and increased by 4.6%.
