Analysis on Temparal and Spatial Distribution Characteristic of Mud-rock Flow and Landslide with the Rainfall Condition

By analysis about temporal and spatial distribution characteristic of mud-rock flow and the landslide with the rainfall condition in Tibet 1970 ~2006 year, Concluded that the Tibet area mud-rock flow and the landslide mainly occurs in eastern Tibet, the Himalaya Mountains south side and along Yarlung Zangbo River line, the annual June-August were the most period of the mud-rock flow and the landslide occurrence, the rainfall is the main meteorological condition that induces the mud-rock flow and the landslide, it's close correlation that the occurrence possibility of the mud-rock flow and the landslide with the different rain type, the different rank rainfall and the preliminary rainfall situation.This research conclusion provides the reference for Tibet mud-rock flow and the landslide early warning and forecast.
