江西油岭3种南方红豆杉植被群系空间点格局分析
Spatial Point Pattern Analysis of Three Taxus wallichiana var.mairei Vegetation Formations in Youling,Jiangxi
摘要
Abstract
In order to explore the space association of the endangered plant Taxus wallichiana var.mairei population with other tree species in the vegetation community of Jiangxi Province,three forest plots with relatively abundant Taxus wallichiana var.mairei within the Taxus wallichiana var.mairei Nature Reserve in Youling of Jiangxi Province were selected for quadrat surveys,the spatial point pattern method was used to analyze the spatial pattern of the Taxus wallichiana var.mairei population and its spatial association with dominant species,and the spatial distribution differences of Taxus wallichiana var.mairei in different vegetation communities were compared.The result showed that of the three vegetation formations(Cunninghamia lanceolata mixed forest,Phyllostachys edulis forest and Taxus wallichiana var.mairei mixed forest)the saplings of Taxus wallichiana var.mairei were clustered or randomly distributed,while the adult trees of Taxus wallichiana var.mairei were slightly clustered;the saplings of Taxus wallichiana var.mairei were clustered with Cunninghamia lanceolata while the adult trees of Taxus wallichiana var.mairei were randomly distributed with Cunninghamia lanceolata;the saplings of Taxus wallichiana var.mairei were randomly distributed with Phyllostachys edulis while the adult trees of Taxus wallichiana var.mairei were significantly mutually exclusive.According to the results of spatial analysis,Taxus wallichiana var.mairei could grow smoothly in the vegetation formations of Cunninghamia lanceolata mixed forest,Phyllostachys edulis forest and Taxus wallichiana var.mairei mixed forest,but there was a strong spatial exclusion between adult trees of Taxus wallichiana var.mairei and Phyllostachys edulis.The results confirmed that the saplings of Taxus wallichiana var.mairei could be mixed with Cunninghamia lanceolata and Phyllostachys edulis,but they competed with the latter in the process of growing into adult trees,and certain spatial niches were required.关键词
