摘　　要：以呼图壁河流域石门水文站以上山区河道为研究区域,利用石门站2015—2019年的日流量观测数据和1978—1983年、2008—2019年的年平均流量数据,以GFS降水资料为WRF-Hydro模型的输入,用其内置的扩散波模式、马斯京根-康吉模式两种河道演算方式进行径流模拟,对比分析模拟径流与实测径流的差异,探讨基于WRFHydro模型的洪水演进方法在新疆内陆干旱区的径流模拟效果。结果表明:扩散波模式模拟效果总体优于马斯京根-康吉模式的模拟效果。分析了WRF-Hydro两种河道演算模式模拟洪水的一些特征,其中扩散波模式模拟结果较好,用时较长;马斯京根-康吉模式模拟结果不太理想,但用时短。We applied the two built-in channel routing methods of the WRF-Hydro model(i.e.,the diffusive wave and the Muskingum-Cunge methods)to the upstream area of the Shimen Hydrological Station in the Hutubi River Basin and used GFS precipitation data for model input.The difference between the simulated and measured runoff was compared and analyzed using daily flow observations from 2015 to 2019 and annual average flow data from 1978-1983 and 2008-2019 at the Shimen Hydrological Station.We also discussed the simulation effect of the flood evolution method based on the WRF-Hydro model in the Xinjiang inland arid mountainous area.The results show that the simulation effect of the diffusive wave method is generally better than that of the Muskingum-Cunge method.This paper analyzes some characteristics of the two river routing models of WRF Hydro to simulate floods.The diffusive wave method had better simulation results,but took longer,whereas the Muskingum-Cunge method had less ideal simulation results,but went faster.
