泥石流是天山主要自然灾害之一。天山泥石流按触发因素可以分为暴雨型泥石流和冰川型泥石流两类。目前天山泥石流主要对交通运输造成灾害,在部分地点对厂矿企业和居民点造成灾害。天山泥石流的形成和发生有其特点,掌握其形成条件和过程特点有利于减轻自然灾害。

Debris flow is one of the most serious natural hazards in Tianshan Mountains.According to trigger agent,the debris flows can be divided into storm type which is caused by strom flood,and glacial type which is caused by flood from melting of snow and glacier in hot weather.At present,debris flow causes damage mainly to transportation,sometimes to mining and residents in the mountainous area.The catastrophic process and the forming condition of the debris flow show regional regularity,therefore,the research of its distribution,processes,and environmental condition is useful in mitigating the natural hazard.
