Abstract:Research purposes:The landslide is unevenly distributed in China,and there is big difference in the landslide intensity among the provinces due to the different geological environments and human environment.In order to master development degree of landslide disaster in China,the study was done on the contribution rate of landslide intensity of the different provinces through 737 landslide samples with their landslide volumes between 5×10 and 2.5×107 m3collected from 31 provinces in China.
Research conclusions: The contribution rates of landslide intensity of 10 provinces,including Sichuan,Chongqing,Hubei,Gansu,Shaanxi,shanxi,Guizhou,Hunan,Xizang,and Yunnan are high with distribution rate up to 60.1% of the total distribution rate,and they belong to the high intensity regions of landslides. The distribution rate of landslide of the another 11 provinces,including Liaoning,Xinjiang,Jiangxi,Jiangsu,Ningxia Heilongjiang,Tianjin,Jilin,Shandong,Hainan,and Shanghai are low with rate up to 13.4% of of total rate and they belong to the low intensityregions of landslides. After the study on the contribution rate of landslide intensity of each province in China,this paper presents an efficient classification of landslide intensity for providing the references to the construction programs and the landslide prevention.
