Analysis of the Community Structure and Regeneration Status of Fagus pashanica on the Micang Mountain

Relatively complete natural evergreen and deciduous broad-leaved mixed forest types of Fagus pashanica are found in medium mountainous zone in the northern margin of the Sichuan Basin. Studies were made of the community structure and status of Fagus pashanica on Micangshan Mountain. The results showed that ①Fagus pashanica canopy was neat, having tree layer, shrub layer, herb layer and the moss layer; Fagus pashanica was main dominant tree species. ②In Fagus pashanica natural forest communities, its growing season had warm and humid features, community phanerophytes had the largest distribution, accounting for 56.4%, followed by hemicryptophytes, accounting for 35.1%. ③ Fagus pashanica DBH and age classification showed a symmetrical distribution, Fagus pashanica seedling number per hectare was more than 2 800,displaying the stability of the community structure.
