Abstract:
The Markovian model was applied to predict the changes of coverage and species diversity at each stratum (tree,shrub and herb, resistively)of the detsriorated Pinus massoniana forests under improvement and also the changes of speific composition of the shrub stratum in the forests in Sichuan Basin. The results indicated that the Markovian model could be applied to study the artificial restoration and reconstruction of the deteriorated forest ecosystem.In the Sichuan Basin,the deteriorated P. massoniana forests could be naturally regenerated,and the restoration could be speeded up if conservation and replantation were taken. The Markovian model and its prediction results are discussed in this paper.
