处于变形中的滑坡体上生长的树木，生长过程中会受到滑坡活动的影响，最为典型的表现即树干弯曲生长，形成“马刀树”。马刀树是滑坡缓慢滑动的历史证据。从滑坡地表马刀树的枝干生长弯曲特征出发，构建基于地表树木生长特征的滑坡形成演化分析方法：以一段历史时期内树木倾倒、弯曲生长的特征所对应的滑坡变形过程，根据坡面不同部位树木的弯曲特征对滑坡进行研究。并将这一方法应用于四川省理县二古溪滑坡的研究中，得到二古溪滑坡不同部位土体滑动情况以及现今变形状态，重建滑坡活动历史，计算得到上一次明显滑动的时间。

The growth process of trees growing on the landslides will be affected by landslide activities. The most typical result is the bent trees. The bent trees are historical evidence to prove that the slope has ever been slided slowly. This paper started from the bending characteristics of trees on the landslide and put forward a method to an-alyze the formation and evolution of landslide based on growth characteristics of trees on the slope. The deformation process of slope that corresponds the bending characteristics of trees during a period of time is analyzed ,then the regionalization research of the landslide is carried out according to the bending characteristics of trees located in dif-ferent areas. The method was applied to the research of Erguxi Landslide,Lixian County,Sichuan Province. The result showed the sliding state of each area of the landslide and deformation state nowadays. The activity history of the landslide was rebuilt and the time of last significant sliding was determined by calculating.
