Characteristics and succession rules of vegetation types in Changbai Mountain

Abstract

Vegetaion characters and succession rules were generalized,based on the investigations and long-term positional observation in.the Changbai Mountain,the property,composition,structure and distribution of Changbai Mountain’s zonal and azonal vegetation types were described in detail.The relationship between vegetation succession of Changbai Mountain and volcanic outbreaks were discussed.Pinus koraiensis-Abies holophylla broad-leaved mixed forest is considered to be the vertical distribution baseband of Changbai Mountain vegetation,and it is also the zonal vegetation type of Changbai Mountain.Chronically influenced by human activity,zonal vegetation was weakened and large area of natural secondary forest and farmland were formed.To restore zonal vegetation,zonal tree species should be introduced,and stabilized and proper structural forest community structure should be established.
