摘　　要：丹江口水库是南水北调中线工程的核心水源区,具有重要的战略意义及独特的生态结构。为了模拟丹江口水库三维水动力过程,掌握水位、水温等水力要素的变化规律,服务于丹江口水库管理和水质模拟,采用环境流体动力学模型(EFDC)建立丹江口水库三维水动力模型,对丹江口水库2012年水位及流场、水温进行模拟,并将水位和水温模拟值与实测值进行对比,发现两者较为接近,表明丹江口水库三维水动力模型精度较高,适用性强。由模型模拟结果可知,丹江口水库2012年坝前水位变化较大,而水库水温分层现象在夏季最为明显,春秋季减弱,冬季基本丧失。Danjiangkou Reservoir is the core water source for the Middle Route of the South-North Water Diversion Project,which has impor-tant strategic significance and unique ecological structure.In order to simulate the three-dimensional hydrodynamic process of Danjiangkou Reservoir,learn the changing rules of the hydraulic elements such as water level,water temperature and serve Danjiangkou Reservoir man-agement and water quality simulation,this research established a three-dimensional hydrodynamic model based on the Environmental Fluid Dynamics Code(EFDC).Meanwhile,it performed a simulation on water level and flow field,water temperature of Danjiangkou Reservoir in2012,the simulated water level and water temperature were in good agreement with the observed values,which showed high precision and strong applicability of the model.As shown,the water level in front of Danjiangkou Dam changed greatly in2012;Danjiangkou Reservior's phenomenon of water temperature stratification was most obvious in summer but weakened in spring and autumn,and disappeared in winter.
