【 摘 要 】

China is a country with frequent mountain flood disasters. Especially in recent years, with climate change and social population develops rapidly, mountain torrent disaster not only cause huge economic losses, but also cause injuries to people. So the prevention and treatment of mountain torrent disaster get more and more important. This paper starts from non-structural measures of mountain flood prevention, it chooses Wendeng, Shandong as an example, considering the topography and hydrometeorology of Wendeng basin, analysis the hydrological characteristics of this basin, this paper constructs topology of Wendeng Basin, establish distributed hydrological model of Wendeng Basin. In this paper, the intensity of various disaster-causing factors and the vulnerability of disaster-bearing body in each basin of Wendeng area were analysed by taking the basin as a unit. Then through the superposition analysis, the distribution of risk in each river basin was finally obtained, which provided the basis for the prevention and control of mountain flood in Wendan City.
