Hazard Zoning of Landslide and Debris Flow Disasters in Yunnan Province
摘要
Abstract
According to the Yunnan landslide and debris flow disaster environment and inducing factors, select the elevation, slope of terrain, annual heavy rain days, annual rainstorm days and critical rainfall as influence factor in this paper; using daily precipitation data of 124 stations in Yunnan during the period of 2000 -2011, the landslide and debris flow cases and 1: 250, 000 scale Yunnan terrain data, the susceptibility coefficient between these factor attributes and landslide and debris flows was calculated, and using the principal component analysis method to establish the model of zoning, the susceptibility of landslide and debris flow of all influence factors were integrated, Finally completed the hazard zoning map of landslide and debris flow in Yunnan Province with the GIS tools. The zoning results show that high risk region is mainly distributed in the northwest, northeast and southwest of Yunnan, it is consistent with the activities of landslide and debris flow in Yunnan, and discussed about the forecast method of landslide and debris flow.关键词
