Species composition and community structure of deciduous broad-leaved forest in Wucheng Nanshan Nature Reserve,Zhejiang Province
摘要
Abstract
[Objective]The Wucheng Nanshan Nature Reserve in Zhejiang Province belongs to the mid-subtropical evergreen broad-leaved forest zone in the vegetation zone,while the typical deciduous broad-leaved forest community is distributed in medium and high altitude area,which is the forest ecosystem under the protection of the Reserve.By analyzing the species composition and community structure characteristics of the 1 hm2 forest plot in Nanshan Nature Reserve,this study provides scientific basis for the protection and dynamic research of biodiversity and characteristic vegetation resources in the nature reserve,and also contributes foundational data for the study of deciduous broad-leaved forest communities in the subtropical areas of China.[Method]Based on the survey data from 1 hm2 forest plot in the Nanshan Nature Reserve,species composition,flora characteristics,the species diversity index,diameter class structure and vertical structure of the community were analyzed.[Result](1)There were 97 woody species belong to 39 families,65 genera(3 gymnosperms species belong to 3 families and 3 genera,94 angiosperms species belong to 36 families and 62 genera),among which Rosaceae,Ericaceae and Lauraceae accounted for the largest number of species.(2)From a perspective of the flora,the temperate component was approximately 1.63 times as much as the tropical component at the generic level,and the temperate component was dominant.(3)A total of 11 019 woody individuals were found in the plot.Quercus serrata,Rhododendron simsii and Sorbus folgneri were the top three dominant species in the community.The important values of the deciduous species,evergreen species and coniferous species were 0.709,0.180 and 0.111,respectively,indicating that the community was a typical deciduous broad-leaved forest.(4)The DBH size-class distribution followed a reverse"J"shape with an average diameter of only 3.66 cm,and the individuals at the minor diameter class accounted for 95.16%of the total population.(5)The proportion of plants in shrub layer,sub-canopy layer and canopy layer was 73.79%,23.44%and 2.77%,respectively,indicating that shrub plants occupied a higher proportion in the vertical structure and the forest canopy layer was not obvious.[Conclusion]Nanshan forest plot in Zhejiang Province is a typical deciduous broad-leaved forest with rich species diversity and high plant density,but the plant diameter class in the community is generally small and the vertical structure is not obvious.This community is representative in the middle and high altitudes of the mid-subtropical regions.关键词
