| 摘 要： | 通过对云南普洱地区季风常绿阔叶林演替15年、30年及原始林群落的调查,探讨了不同演替阶段群落的物种-面积关系.结果表明:不同演替阶段群落中,取样面积与总物种数,乔木、灌木和藤本物种数均具有极显著相关关系,其变化解释率均超过94%;演替30年群落中总物种和乔木的物种累积速率(Z)最低(0.334和0.394),演替15年群落中灌木和藤本的Z值最低(0.437和0.326);不同演替阶段中总物种、乔木、灌木和藤本的物种-面积曲线截距无显著变化,但原始林中总物种和藤本物种-面积曲线的决定系数(R2)显著高于演替15年和30年群落.演替15年群落中,初始乔木及灌木物种丰富度解释了Z值变化的99.9%,而其他演替阶段群落中初始乔木、灌木、藤本及总物种丰富度与Z值均无显著相关性.

| Abstract: | Based on the investigation data of monsoon evergreen broad-leaved forest at its different succession stages(primary,CP;15 years of succession,CF;and 30 years of succession,CT) in Pu'er of Yunnan Province,this paper studied the species-area relationship of this forest at each succession stage.It was found that in the communities at each succession stage,the number of total species,trees,shrubs,and lianas had a significant correlation with sampling area,with the area explained over 94% of the total variation.... |
