Abstract: During the past years, from 1958-1963, it has been the gobd fortune of the writet to Study on the composition of populations designed in the permanent quadrats at the Yunnan Biogeocoenological Station of Tropical Forest. It is author's aim to research the real state of different populations in this com-munity.Basal on this,the author has calculate its process of historical development and the possibility of futural xevolution, which can give a basis for managing this tropical forest.

摘要： 种群是群落中某一植物种的全部个体的总和。热带雨林中的种群系指组成该雨林的全部植物种的种群个体。在群落学研究中，不少学者认为在某种群落条件下，研究从种子发芽到个体死亡。种的个体发育及种群整体，对于认识植物群落有很大的意义。若能有效地鉴定组成群落的所有种群的全部成分，并确定其年龄成分，就可能比较正确地认识该群落的过去、现在和将来。目前对于群落种群的研究报道不多，至于热带雨林中种群配置的报道尤为少见。
