Abstract:

Based on the interspecific association, main component analysis, division method of optimization, and Markov succession model, the secondary succession of Pinus massoniana community on the natural condition in the mountainous county, Chun'an, Zhejiang Province was quantitative analyzed. The results showed that ①during the natural recovery process,4 tree species such as Pinus massoniana, Dalbergia hupeana were declined, 9 species such as Castanopsis carlesii, Lithocarpus heryi, Liquidambar formosama were transient species, 4 species such as Castanopsis Sclerophylla,Schima superba were progressive species. ②the succession process was divided into four stages:stage 1, pure massoni forest, stage 2, the needle broad leaved mixed forest dominated by masson pine, stage 3, needle and broad leaved mixed forest dominated by broad leaved species, stage 4, evergreen broad leaved forest dominated by Castanopsis sclerophylla,Schima superba and Cyclobalanopsis glauca. ③ the secondary succession was predicted by Markov model that about 25 years were essential for every stage, and 80～100 years were necessary for the recovery of mesophilous evergreen broad leaved forest.
