MIKE SHE分布式水文模型在秦岭北麓地区适用性研究

Applicability of MIKE SHE Distributed Hydrological Model in the Northern Foothills of Qinling Mountains

通过分别搭建峪口以上空间中尺度模型,开展参数敏感性分析和率定验证工作,同时以涝峪口、大峪峪口、罗李村水文站位置为倾泻点,划分流域范围,搭建涝峪、大峪、罗李村的空间小尺度模型。结果表明:MIKE SHE模型在峪口以上流域及各小流域具有较好的适应性,径流年内变化模拟过程与水文站数据拟合程度较好且内径流变化与降雨量过程具有明显的同步关系。

Through the establishment of spatial mesoscale models above Yukou,the sensitivity analysis and calibration verification of parameters were carried out.At the same time,the locations of the hydrographic stations at Laoyukou,Dayuyukou and Luoli village were taken as the dumping points to divide the watershed area and build spatial small-scale models for Laoyukou,Dayu and Luoli village.The results show that the MIKE SHE model has good adaptability in the catchment above Yukou and other small catchments,and the simulation process of annual runoff variation fits well with the data of hydrological stations,and the internal runoff variation has obvious synchronization relationship with the rainfall process.
