Community Characteristics of Larix mastersiana in Sichuan Gonggangling Provincial Nature Reserve
摘要
Abstract
In order to protect the wild germplasm resources of Larix mastersiana,the endemic tree species in China,and maintain the habitat and species diversity of native tree species,the investigation of Larix mastersiana community was carried out in the Sichuan Gonggangling Provincial Nature Re-serve by means of line transect method and quadrat method.The results showed that:(1)Larix mas-tersiana has a discontinuous sporadic distribution and low population density in the reserve;(2)the vegetation type of Larix mastersiana distribution area is cold-temperate coniferous forest,and the formation is divided into Larix mastersiana forest and Picea asperata forest.The community types could be divided into 5 classes.(3)110 species of vascular plants of 76 genera in 43 families were in-vestigated in the community.Among them,2 families,2 genera and 2 species are ferns;(4)there are faults in the age structure of Larix mastersiana population.There were far more seedlings than sap-lings,which resulted in poor natural regeneration.关键词
