| 中文摘要: |
| 金沟河是以融雪为主要补给水源的山区性河流，为了更好地指导流域的水资源分配工作，在借助金沟河流域水文气象数据、DEM数据与MODIS数据的基础上，利用融雪径流模型进行金沟河流域的融雪径流模拟研究。研究结果表明：（1）SRM模型在金沟河流域具有良好的适用性，流域2009年4-9月份的拟合优度确定系数与体积差分别为0.87与2.0%，基本达到模型在其他流域应用的平均水平。（2）模型汛期峰值与峰值出现时间模拟出现偏差，汛期径流补给来源较为复杂。模拟结果可为金沟河流域径流预测提供一定的参考依据。 |
| 英文摘要: |
| Jingou River is a mountainous river with its streamflow mainly from snowmelt water. In order to better guide the distribution of water resources in the basin, based on the hydrological and meteorological data,DEM data and MODIS data,SRM model was used to simulate the snowmelt runoff in the basin. The results show that:(1) SRM model had a good applicability in Jingou River Basin. The coefficient of fitting goodness and the volume difference of the basin from April to September 2009 were 0.75 and 9.57%, respectively, which basically met the average level of the application of the model in other basins. (2) The deviation of peak value simulation in flood season was mainly due to the instantaneous snowfall in Jingou river basin at the end of June 2009. The simulation results can provide some reference for runoff prediction of Jingou River Basin. |
