Characteristics of plant community diversity in different vegetation restoration periods in the central subtropics
Taking the residual forest,coniferous and broad mixed forest and broad-leaved forest in Yangdi Forest of Ganjian-gyuan National Nature Reserve as the research object,the method of spatial sequence instead of time series was used to ex-plore the plant diversity and stand structure characteristics of different vegetation recovery periods,so as to provide a theoret-ical basis for the vegetation restoration in subtropical areas.The results show that the plant species in different vegetation storation periods were broad-leaved forest(38 species),coniferous and broad-leaved mixed forest(28 species),and residual forest(23 species).With the progress of vegetation restoration,the species of trees and shrubs increased,and the species of herbaceous plants increased first and then decreased.There were significant differences in the importance value,α diversity and similarity of trees,shrubs and herbs in different vegetation restoration stages.Community succession promoted the growth of trees and shrubs,and inhibited the growth of herbs.This study provides a reference for the protection of plant diversity and the stability of subtropical plantation ecosystems.
