THE SYNCHRONOUSLY-ESTABLISHED SUCCESSION AND MODEL PREDICTION OF FOREST COMMUNITY ON MOUNT JINYUN OF SICHUAN,CHINA
四川缙云山森林群落的同期发生演替及其模型预测

The synchronously-established succession is the process that pioneer, serai, and climax species grow altogether at the same time, reaching the mixed forest of masson pine and broad-leaved species firstly, then through a series of successional stages, finally developing into the climax community where the primary vegetation was destroyed. With examples in this paper, it illustrated that there was typical synchronously-established succession on Mount Jinyun. The process of succession is stochastic because the invasion of the initial species is stochastic, but the final stage of succession is the same. Markovian model is used to analyse two kinds of synchronously-established succession, the conclusion is that the final stages are evergreen broad-leaved forests with similiar species composition, i. e. the succession is convergent.
