缙云山森林次生演替序列优势种群的生态位

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，基础生态位则相反

The niche of dominant populations in forest secondary sere in Mt.Jinyun

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.
