摘　　要：以所归结的云南83个"成熟阔叶林分"的调查资料为依据,从以下5个方面论述了分布于云南各水系不同"海拔梯级"的由多科多种群林木组成的阔叶林分系统的耗散结构特性,(1)云南阔叶林分的生态阈限范围;(2)云南阔叶林分系统的状态转移概率;(3)用逻辑斯谛方程刻画云南阔叶林分系统的进化过程;(4)用耗散结构论来刻画云南阔叶林分系统由初态走向稳恒态;(5)用马尔科夫过程来说明云南阔叶林分系统的无后效性和时齐性。We used the data obtained from 83 matured broad-leaf stands to explore ： （ 1 ） the limitation of ecological distribution of these trees ; （2） their stand transition rates ; （3） evolutionary processes of the broad-leaf stands, described by logistic equation; （4） initial state toward stable state described by the dissipative structures; （5） to describe non-lagging and timing with Markov process. These stands are distributed along different altitudes and with diverse constitution of trees, in which the dissipative structure is described.
