摘要:

通过研究卵叶桂种群的生态位特征,为其种群的恢复与保护提供理论依据。采用定量分析方法,对尖峰岭山地雨林5个群落的卵叶桂与优势种的生态位进行研究,结果表明:1)同一群落的优势种生态位宽度越大,物种对生态因子的适应幅度就越大,在群落内有广泛的分布且较为均匀;而重要值大的优势种其生态位宽度值不一定大。2)卵叶桂的生态位宽度处于中等以上,表明其在山地雨林具有较强的适应能力和对环境资源有较充分的利用。3)在更新林群落,卵叶桂与阳性优势种的竞争较为激烈,随着演替的进展,竞争激烈程度也逐渐降低;在原始林群落,卵叶桂与耐阴树种的生态位重叠较大,对资源的利用较相似,在原始林群落中常为伴生树种。

Abstract:

By studying the niche characteristics of Cinnamomum population,this paper provided a theoretical basis for its population restoration and protection.Quantitative analysis method was used to study the niche of Cinnamomum and dominant species in 5 communities of Jianfengling mountain rainforest,the results show that:1)The greater the niche breadth of dominant species in the same community,the greater the adaptation range of species to ecological factors,which were widely distributed and more even in the community;However,the niche breadth of dominant species with high important value was not necessarily large.2)The niche width of Cinnamomum was above medium,indicatsing that it had stronger adaptability in mountain rainforests and mades full use of environmental resources.3)In regeneration forest community,Cinnamomum and thelight-loving dominant species had more intense competition,with the progress of succession,the intense degree of competition also gradually decreased.In the primeval forest community,the niche overlap of Cinnamomum and shade-tolerant tree species was greater,and had more similarities in resources utilization,which was often associated tree species in primary forest communities.

Key words: Jianfengling, different communities, Cinnamomum, dominant population, niche
