Abstract:

Taking the natural secondary forest in Pingtan Island as the research object,this paper analyzed the changes of species composition,important value and species diversity of shrub-grass,coniferous forest,mixed wood and broadleaf forest and discussed community species diversity differences among Pingtan Island and surrounding islands and land areas.The results showed that there were 53 families,89 genera and 104 species in the four forest.Margalef index,Shannon-Wiener index and Pielou index of the community types and the various levels showed an upward trend from shrub-grass to mixed wood,and a downward trend in broadleaf forest.The change of Margalef index,Shannon-Wiener index at the various levels was as follows:tree layer was mixed wood>broadleaf forest>coniferous forest,shrub layer was mixed wood>coniferous forest>broadleaf forest>shrub-grass,and herb layer was mixed wood>broadleaf forest>coniferous forest>shrub-grass.In one-way anova,the Margalef index,Shannon-Wiener index and Pielou index of the tree layer were significantly different between mixed wood and coniferous forests(P<0.05).Shannon-Wiener index of shrub layer and herb layer was significantly different between mixed wood and shrub-grass,broadleaf forest(P<0.05).The species diversity level of Pingtan Island is significantly lower than that of Putuoshan Island and the land areas.

Key words: vegetation succession, community structure, species diversity, species composition, Pingtan Island
