| 为了探究流域水文循环及河道水动力变化规律，根据收集到的基础数据资料，基于MIKE SHE模型构建沙河水库流域分布式水文模型，模拟流域径流过程，并根据物理参数意义及率定的方式确定了模型相关参数。研究结果显示：MIKE SHE模型在研究区具有良好的适应性，2018年全年径流过程Ens达到0.75，R2为0.77，径流总量RE为1.3%；汛期（6～9月）径流过程Ens为0.71，R2为0.73，径流总量RE为7.5%，模拟精度达到良好水平，可为流域层面水环境模拟提供基础支撑，也可为其他相似地区水文模拟提供参考。 |

| In order to explore the hydrological cycle and hydrodynamic behavior of river channels,based on the collected fundamental data and MIKE SHE model,this paper constructed a distributed hydrological model of Shahe reservoir watershed to simulate the runoff process and determine relevant parameters of this model according to the significance of physical parameters and the calibration method.The results show that MIKE SHE model has good adaptability in the research area.In 2018,the annual runoff process Ensis 0.75,R2is 0.77,and the total runoff RE is 1.3%;In flood season（June-September）,the runoff process Ensis 0.71,R2is 0.73,and the total runoff RE is 7.5%.The simulation accuracy reaches a good level,which can provide basic support for water environment simulation in Shahe reservoir watershed and a reference for hydrological simulation in other similar watersheds. |
