| 英文简介 | The rivers in arid area of northwest China originate from mountains with high elevation and low temperature. The influence of soil freezing-thaw on streamflow in alpine watershed is an important research project. This study tries to analyze the seasonal soil freezing-thaw regime through a coupled model of soil water and heat, and explore the influence of soil freezing-thaw process on streamflow through modifying the snowmelt-runoff model. The modified snowmelt-runoff model combines the coupled model of soil water and heat and hydrological model based on System Dynamic principles. In this study, the discipline of the seasonal soil freezing-thaw process and the relationship between surface runoff and rainfall and snowmelt water are going to be analyzed by designing field experiments in Banchangou of Gongnaisi River Basin. The coupled model of soil water and heat is going to be built by analyzing the soil freezing-thaw process. The interpolation method is going to be used for interpolating the soil freezing-thaw process from stations to watershed level. The runoff process and the influence of seasonal soil freezing-thaw process on streamflow are going to be simulated by the modified snowmelt runoff model which combined the coupled model of soil water and heat and hydrological model. |
