Abstract: Therefore，one debris floWwhich happens on the campus of Chongqing College of Arts and Sciences is taken as an example to analyze the formation mechanisMof debris flow，according to territorial environment geology，hydrology and engi- neering geology conditions．This analysis is considered as one part of“distribution characteristics of debris floWand its pre- vention measures in Chongqing”project．The debris floWcharacteristics in different zones are investigated at first．Then the formation mechanisMof debris floWis analyzed．Finally，the countermeasures against the debris floWare discussed，which provides the reference for the prevention and control of the debris floWin similar territorial conditions．

Key words: words：debris flow, volume of rainfall, formation mechanism：control measures

摘要： 结合“重庆市泥石流的分布特征及其防治措施”项目，以重庆文理学院卫星湖校区后山泥石流为例，采用一定 的工作手段，调查区域环境地质、水文地质、工程地质条件，查明泥石流各区特征，分析形成机制，并对处治方案进行 了探讨。为类似地质环境条件下泥石流预测、防治提供了借鉴。
