Abstract:

The space distribution,species diversity,species association degree and forest floor dynamics in Changan Forest Park of Fuzhou were studied and analyzed through field investigation and statistics.The results showed that:(1)the herb layer has the most uniform distribution,and the second one is tree layer,while the last one is shrub layer;(2)the species of shrub layer possesses the most diversity of species and community,and then is the tree and herb layer.But the correlation between species is poor.;(3)the number of species in the regeneration layer is relatively small,and the species is simplex which will not be conducive to the development of the forest.The species richness and abundance of the succession layer is beneficial to the forest.The study concluded that the correlation between Changan Forest Park is poor which is in the primary succession stage and needs to be further transformed.

Key words: Changanshan Forest Park, species diversity, community structure, succession
