| 摘 要： | 植物种群的生态位宽度与种群之间的生态位相似性比例及生态位重叠度反映了森林的更新生态特征。采用定量分析方法对子午岭油松林主要种群的更新生态位进行分析研究,结果表明:油松林林下主要种群生态位宽度值在中间范围,但辽东栎种群则为广生态位种;油松林林下主要种群之间生态位重叠度均很小,宽生态位种群对资源具有一定共享性,而窄生态位种群则各自集群分布。

| Abstract: | The ecological characteristics of natural forest are affected by niche breadth,niche proportional similarity and niche overlap.The regeneration niche of main tree populatins in Pinus tableformis community are analyzed by using quantitative method in Ziwuling Mountians.The result shows that most tree populations of Pinus tableformis community belong to moderate niche breadth except Quercus liaotungensis population.All the niche overlaps between populations are limited.The population with wide niche breadth could share the same resources,while the one with narrow niche breadth is distributed concentratively. |
