Abstract:

Based on the sampling data, species richness, species diversity index and evenness index of plant communities in Wuyishan national nature reserve were discussed. The change law of community diversity in Wuyishan national nature reserve were as follows: species richness, species diversity index and evenness of plant communities increased along with the vegetation succession trend from needle leaved forest, needle broad leaves mixed forest to evergreen broad leaves forest with large variation among communities; the species richness, species diversity index and evenness of plant communities in different growth form all were in the following order: shrub layer>tree stratum. Phyllostachy heterocycla cv. pubescens community as an important vegetation, its species diversity in shrub layer was higher than that in other three communities; species diversity in tree stratum was obviously lower than that in other three communities, because of Phyllostachy heterocycla cv.Pubescens asexual propagation and its dominance in community.

Key words: Wuyishan national nature reserve, Species diversity
