| 摘 要： | 通过对1970～2006年西藏泥石流、滑坡的时空分布特征与降水条件分析，得出西藏地区泥石流、滑坡主要发生在藏东地区、喜马拉雅山南侧及沿雅鲁藏布江一线，每年6～8月是泥石流、滑坡多发时段，降水是诱发泥石流、滑坡的主要气象条件，发生泥石流、滑坡可能性与不同雨型、不同等级降水和与前期降水情况密切相关。该研究分析结论，为西藏泥石流、滑坡预警预报提供了参考依据。

| Abstract: | 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,i... |
