Differences in community characteristics of evergreen broad-leaved forests between Baishanzu National Park and adjacent areas
摘要
Abstract
[Objective]Baishanzu National Park has a typical and complete subtropical forest ecosystem with a comprehensive vertical spectrum and extensive primary evergreen broad-leaved forest.By comparing the community structure and species diversity of the evergreen broad-leaved forest in Baishanzu National Park with those in other national nature reserves and non-protected areas in Zhejiang Province,this study aims to understand the community characteristics of the evergreen broad-leaved forest in Baishanzu National Park and provide a theoretical basis for the protection of subtropical native evergreen broad-leaved forest and the restoration strategy of degraded vegetation.[Method]This study selected evergreen broad-leaved forests in Baishanzu National Park(including Fengyangshan and Wulingkeng),Jiulongshan,Wuyanling,and Gutianshan National Nature Reserve,as well as a non-nature reserve area as the research sites.A total of 50 plots of 30 m×30 m were set up.By calculating the species diversity index and biomass of all woody plants,mature trees and saplings with DBH≥1 cm in these plots,through methods including Analysis of Variance(ANOVA),Principal Coordinate Analysis(PCoA)based on the Bray-Curtis dissimilarity index,and Permutational Multivariate Analysis of Variance(PERMANOVA),we compared and analyzed the species α diversity,species composition and biomass differences of all woody plants,mature trees and saplings in evergreen broad-leaved forest in different sites.[Result](1)A total of 304 species belonging to 128 genera in 57 families were found in 50 plots,among which 241 species belonging to 108 genera in 52 families were found in Baishanzu National Park.Schima superba and Castanopsis eyrei were the dominant species.(2)The species α diversity of all woody plants and saplings was highest in Wulingkeng of Baishanzu National Park.Additionally,the species α diversity of all woody plants,mature trees,and saplings in national parks and nature reserves were higher than that in the non-nature reserves area.(3)Significant difference in species composition of all woody plants,mature trees and saplings were observed between Wulingkeng and Fengyangshan of Baishanzu National Park,as well as between other sites.(4)No significant difference in biomass of woody plants,mature trees,and saplings was found among Fengyangshan,Wulingkeng,Wuyanling and the non-nature reserves area.However,sapling biomass in Wulingkeng and Fengyangshan was significantly lower than that in Gutianshan.[Conclusion]The species diversity,species composition,and ecosystem function of the evergreen broad-leaved forest in Baishanzu National Park differ not only among different areas in the same national park but also with the other subtropical regions.This suggests that the original evergreen broad-leaved forests in Baishanzu National Park exhibit a distinct uniqueness.关键词
