摘要
通过划分青海省主要流域并构建相应SWAT模型,模拟流域日、月平均径流变化过程,根据模型径流模拟值与实测值对比及对模型模拟结果进行评价,从而探讨所构建模型的模拟精度及其适用性。结果表明:SWAT模型不适用于柴达木盆地,而对高寒区或高原区内以降水、冰川、融雪为主要补给的流域的径流模拟效果良好,且具有较好的适用性。
The major basins in Qinghai Province were divided and a SWAT model was built to simulate the change processes of average daily and monthly runoff. The measured values and simulated values of runoff were compared and the model’s simulation results were evaluated,in order to analyze the precision and applicability of the model. The results show that the SWAT model is not applicable to the Qaidam Basin. However, it shows a strong performance and applicability in the basins supplied mainly by precipitation, glaciers, and snowmelt in cold regions and plateau areas.
