Pinus taiwanensis community composition and structure based on fixed sample Daiyun Mountain
摘要
Abstract
Pinus taiwanensis is one of the main groups in the Central Subtropical Mountainous Area.Study on the species composition and community structure is of great significance to discuss the succession law of the subtropical vegetation.There is a large area of P.taiwanensis community in Daiyun Mountain Nature Reserve.We established 86 plots (25.82 m × 25.82 m) by using the grid point method,5.7 hm2 totally, and analyzed characteristics of distribution type, diameter and tree height structure, spatial distribution pattern of P.taiwanensis in the plot.The results were as follows: (1) In the plots there were 32 603 strains of woody plants belonging to 59 families, 108 genera and 219 species.The dominant species of arbor and shrubs layers of P.taiwanensis communities were P.massoniana, Schima superba, Oligostachyum oedogonatum, Eurya groffii, E.rubiginosa et al, accounted for rare species and occasionally species were 33.79%, 25.75% and 45.21%, 24.66% of the total species.(2) The distribution types of tropical species were more than the temperate distribution types of genera, tropical distribution types were mainly in pan tropical type, and temperate distribution type the north temperate zone was the largest in.(3) The inverted "J" type of DBH showed that the update in good condition.The vertical structure of the dominant tree height also showed inverted "J" type or approximate inverted "J" type.Pinus taiwanensis and other dominant trees' height were 4-10 m.The maximum number of dominant shurbs' heigh were 1-2 m, except for Vaccinium carlesii's.It had a large number of individuals at the heigh of 0-1 m.(4) It is calculated that the sample of the dominant species are aggregated distribution and they have different aggregation degrees.P.taiwanensis is the lowest of tree layer and Vaccinium carlesii is lowest of shrub layer.In general that the species composition wear of P.taiwanensis communities in Daiyun Mountain Nature Reserve is rich and in a good condition of update.It reflectes the typical characteristics of the subtropical Alpine coniferous forest.The spatial distribution pattern may be related to the sampling methods and other factors.关键词
