Abstract:The various actions of liana in the ravine tropical seasonal rain forest are more abun-dant than that in the tropical moist rain forest, and the young parts of stems possess variable char-acteristics in filling space. The climbing styles of liana can be divided into three types: self-twiner, climbing depending on other species and compound climbing. All of three actions show the secon-dary features in the succession of liana, and they are the results of longterm evolution and adapta-tion among plants and between plant and environment.
