用Levins生态位宽度及重叠、Feinsing等生态位宽度和Petraitis生态位重叠计测方法 ,处理缙云山森林群落演替系列取样 ,分析栲树种群的生态位特征及动态 .结果表明 ,栲树种群为缙云山森林群落演替顶极群落常绿阔叶林的优势种群 ,其生态位宽度随群落演替过程基本呈增长趋势 ,而资源利用程度却呈“∧”形 ;对于栲树种群和缙云山森林群落其它 1 4个优势种群间在所有 5类群落中的生态位重叠 ,仅栲树种群与典型针阔混交林中的小叶栲、光叶灰木、川灰木、薯豆、白毛新木姜子、广东山胡椒、大头茶、虎皮楠、杉木、马尾松种群上和针叶林中小叶栲、光叶灰木、杉木种群上 ,表现出显著完全特定重叠 .
The Levins niche breadth and overlap, Feinsing niche width and Petraitis niche overlap method were used to analyze the forest community succession series sampled from Jinyun Mountain, and the niche characteristics and dynamics of Castanopsis fargesii were analyzed. The results showed that the population of Castanopsis: The dominant population of the forest community successional climax community in evergreen broad-leaved forest showed that the niche breadth increased with the succession of community succession, but the degree of resource utilization was ∧ -shaped. For the populations of Castanopsis forest and Jinyun Mountain forest community, The niche overlap of all the four dominant populations in all five communities showed that the only dominant species in the four populations was the leafhopper, the leaf-gray-wood, the ash-wood, the potato, the white- Mountain pepper, big head tea, tiger bark, Chinese fir, Pinus massoniana population and coniferous forest ichthyoplankia, light gray wood, and Chinese fir population showed significant complete overlap.
