基于多方法的浑河流域水质模拟研究

Research on Water Quality Simulation of Hunhe River Basin Based on Multiple Methods

为更好地研究浑河水质状况,选取TP和TN两项指标,采用分布式水文模型对浑河水质进行模拟,并考虑模拟结果的合理性,采用输出系数法对浑河流域TP、TN污染负荷总量进行估算,计算结果表明两种方法模拟结果比较接近,说明模拟、估算结果具有一定的合理性。结果可为浑河水质水量联合调度改善水质提供数据基础。

In order to better study the water quality of the Hunhe River,this paper selects two indicators,TP and TN,and a distributed hydrological mode is used to simulate the water quality of the Hunhe River.And considering the rationality of the simulation results,the output coefficient method is used to estimate the total pollution load of TP and TN in the Hunhe River Basin.The calculation results show that the simulation results of the two methods are relatively close,which indicated that the simulation and estimation results are reasonable.The results can provide a data basis for the Hunhe River water quality and quantity joint dispatch to improve water quality.
