Other Abstract

 通过实际观测,获得蒋家沟流域近2a的径流资料,总结出2008—2009年间径流的年内特征。通过收集蒋家沟流域土壤、土地利用和气象数据,用SWAT模型模拟了蒋家沟流域的基流月径流模拟和日径流变化。基流月模拟中旱季的模拟效果比较好,汛期由于泥石流暴发时无法观测流量,导致实测资料不完整,模拟结果比较差。日径流模拟分为旱季和汛期模拟,模拟结果的Nash效率系数和相关系数都在0.7以上,表明SWAT模型可以应用于泥石流流域蒋家沟地区的降雨—产流机制研究。

The flow data of Jiangjia Canyon from 2008 to 2009 was collected and annual variations of the stream flow were analyzed. A database of soil, land use and meteorological parameters was built based on the field survey and experiments, and monthly flows and daily flows were then simulated using the SWAT model in the canyon. The simulations of monthly flows were relatively better in the dry seasons than in the rain seasons, owing to the lack of observations during the rainy seasons when debris flows frequently occurred. Daily flows were simulated separately for the dry seasons and the flood period. The Nash efficiency and correlation coefficients of daily flow simulation in both rain season and dry season were higher than 0.7, which implies that the model can be successfully used in this area. This paper contributes to the study of rainfall-runoff mechanism in Jiangjia Canyon
