塔斯沟是一条老泥石流，位于四川理县塔斯村，属于汶川8.0级地震极重灾区。2010年7月31日复活，突发大型泥石流，造成了较大的危害。在进行应急治理后，由于其具备泥石流突发的必有条件，仍然具有泥石流复活的可能性。在对塔斯沟泥石流现场调查，查明沟域内松散物源分布及稳定性的基础上，对塔斯沟泥石流的发育特征及动力学特性进行分析，重点分析了泥石流的成灾机理和特征。研究表明：塔斯沟泥石流物源丰富，地形易于汇水且主沟坡降大，水源动力足，属易发性泥石流，具备再次发生泥石流的基本条件，建议采用建立导流槽，对极危险区和危险区进行保护。研究对于高寒山区泥石流的防治具有参考意义。

Tasi ditch,which located in Sichuan Qrovince,is an old landslide and belong to Wenchuan M8.0 earthquake disaster zone.This old debris resurrection on July 31 ,201 0,then development into a large landslides suddenly,and became a larger damage.Although people carry out the emergency management along the Tasi Ditch,but still have the possibility of mudslides resurrection in this area,because there have a good condition of debris flow sudden.On the basis of site investigation,find out loose the distribution and its stability of the source domain,the author analysis the development of gully debris characteristics and kinetics characteristics,Analyses the mechanism and characteristics of debris flow.The result show that Tasi Ditch have more rich loose deposits, and have a easy catchment and big grade in terrain main ditch,and have plenty of water power,so that it belongs to the liability debris flow,and have the basic conditions of the mudslide again.In the end,the author recommen-ded to establish a diversion trench,to protect most of danger and the danger zone.The research has reference meaning for alpine mountain landslide prevention.
