| 摘 要： | 较全面地论述了西藏琼结县城滑坡泥石流灾害的形成条件、基本特征，并对其形成机制和危害进行了分析。滑坡为沿古滑带(面)发育多期活动的中型中厚层牵引式土质滑坡，以前缘坍塌和左侧解体为主要破坏形式，为下港泥石沈的产生提供大量固体来源，是一典型的滑坡型泥石流。

| Abstract: | This paper deals with geological features, genetic conditions and mechanism as well as harmfulness of landslide and debris flow at Qonggyai County Town, Tibet. The landslide is a multiphase active retrogressive medium- sized soil one which occurs along an old sliding surface. It is characterized by frontal collapse and left breakup as main destructive form. It is source of the downstream debris flow which is a landslide type debris flow. |
