| 摘 要： | 为分析地形和融雪对水文模拟影响,利用SWAT模型在黄河源区进行1960—1990年水文模拟。二者的影响分别通过对子流域划分高程带和运用融雪模块来体现。研究表明,单独考虑融雪影响或考虑融雪、地形的共同影响下,模拟结果均能达到合格;单独考虑地形的影响下能达到良好。相比融雪影响,地形对流域水量平衡的模拟起主要作用。划分高程带对子流域的气温影响较大,对降水影响小。子流域气温的降低使得蒸散发减小,从而增加产水量,其中地下水增加最多,其次是地表径流和壤中流。地形和融雪的影响使地下水的补给来源改变,调整地下水参数后,最终模拟结果达到优秀。地形和融雪在黄河源区水文模拟中的影响可以为其他高山地区水文研究提供参考。

| Abstract: | To quantify the effect of topography and snowmelt on hydrologic simulation, the (Soil and Water Assessment Tool (SWAT) model is employed for the hydrological simulation in the Yellow River's source region for the period 1960—1990. The topographical effect is determined through the partitioning of subbasins into elevation bands. While, the snowmelt effect is simulated using a snowmelt module. A series of simulations is conducted. The result shows that a satisfactory result of model simulations can be obtained when the snowmelt module applied alone or jointly with the consideration of elevation bands. The model will have a better performance if the topography effect is considered, indicating that topography plays a dominant role in water balance simulations. The model temperature is more sensitive to the partitioning of subbasins than precipitation. A reduced temperature value will lead to the reduction of evapotranspiration from subbasins, and hence increases the water yield of subbasins. Groundwater will get the most yield increase and followed by surface water and lateral flow. The influence of topography and snowmelt is likely to change to the source of groundwater recharges. An excellent simulation result can be obtained through calibrating model groundwater parameters that consider the effect of topography and snowmelt. The study provides valuable information for other hydrologic simulation in mountainous watersheds. |
