摘要
通过1986年和1996年对缙云山森林次生演替序列中四种群落类型的重复调查,用两种公式计测生态位宽度,研究演替序列优势种群的基础生态位和实际生态位.结果表明,实际生态位侧重于物种对特定资源的利用能力,基础生态位侧重于物种的生态幅度.在缙云山森林次生演替序列中,各个优势种群的生态位宽度不同,森林先锋种的最宽实际生态位比演替顶极种窄。
Founoamental niche and realized niche of dominant populations in the foorest scondary sere in Mt.Jinyun was reported,concerning four communities in 1986 and 1996.The result shows:realized niche concerns the resource application capacity of species in a special resource state,and fundamental niche focuses on the ecological amplitude of species.In the secondary sere of forest in Mt.Jinyun,different specieds has varing niche breadth:the maximal realized niche breadth of forest pioneer species is smaller than that of climaxal species,however,it is the reverse case for fundamental niche breadth.
