Spatial Pattern and Interspecific Correlation Analysis of Dominant Species of Guanshan Evergreen Broadleaved Forest Monitoring Plot in Jiangxi Province
摘要
Abstract
[Objective]This study aimed to explore the population pattern characteristics of evergreen broad-leaved forest in Guanshan National Nature Reserve,Jiangxi Province.[Method]Based on the investigation data of the dynamic monitoring sample plot of evergreen broad-leaved forest in Guanshan(12 hm2),Jiangxi Province,the distribution pattern,intergenerational relationship and interspecific relationship of dominant species in the sample plot were analyzed,according to the coordinate information of tree points.[Result](1)The dominant species were mainly concentrated,and 90%of the species were concentrated within 25 m,but with the increase of the scale,the tree species gradually turned to random distribution;(2)Among the dominant tree species,the large trees of most evergreen tree species were positively correlated with small trees,such as Daphniphyllum oldhamii and Schima superba;while,the large trees and small trees of deciduous species were negatively correlated,such as Alniphyllum fortunei and Choerospondias axillaris;(3)The dominant species mainly existed in the form of negative correlation,and only 5 species pairs were found to be positively correlated.[Conclusion]The community is still in the early stage of development,the dominant species are mainly concentrated and distributed,and the interspecific competition is fierce.关键词
