摘　　要：热带森林因具有很高的生物多样性和强大的生态服务功能而成为全球生态学研究的热点。然而,针对不同林分起源森林群落特征和碳储量之间的差异的研究报道却比较少见。本研究以海南霸王岭林区人工促进更新次生林(PF)、天然次生林(SF)和原始林(VF)3种不同起源的林分为研究对象,针对其群落的物种组成、群落结构、生物量和碳储量进行差异性分析,结果表明:(1)物种的丰富度大小为VF>SF>PF,径级分布均呈反“J”字型,表现为更新层>演替层>主林层的稳定的群落结构;(2)3种起源的林分乔木生物量大小排序依次均为:干>根>枝>叶,各生物量在径级分布上存在差异,PF、SF和VF各径级的生物量排序分别为Ⅱ>Ⅲ>Ⅰ>Ⅳ,Ⅳ>Ⅱ>Ⅲ>Ⅰ和Ⅳ>Ⅲ>Ⅱ>Ⅰ;(3)3种林分的乔木碳储量为105.01~199.47 t.hm^(-2),其中原始林碳储量最大,人工促进更新次生林最小,人工促进更新次生林乔木碳储量主要分布在径级Ⅱ的树木中,天然次生林乔木碳储量主要分布在径级Ⅱ和Ⅳ的树木中,原始林乔木碳储量主要分布在径级Ⅳ的树木中。研究结果可为热带林业经营管理、森林碳监测和评估提供理论支撑。Tropical forests have become the focus of global ecological research because for their high biodiversity and powerful ecological service functions.However,there hardly are reports on the differences between forest community characteristics and carbon storage of different origin stands.In this study,3 stands of artificial regeneration secondary forest(PF),natural secondary forest(SF)and primary forest(VF)in Bawangling of Hainan Province were taken as the research objects to study the species composition,community structure,biomass and the carbon storage differences of their communities.The results showed that:(1)The species richness was ranked as VF>SF>PF,and the diameter class distribution was inverted"J",showing a stable community structure as regeneration layer>succession layer>main forest layer.(2)The order of biomass of the 3 origin stands was stem>root>branch>leaf,but there was difference in the distribution of biomass in diameter class.The order of diameter class biomass of PF,SF and VF wasⅡ>Ⅲ>Ⅰ>Ⅳ,Ⅳ>Ⅱ>Ⅲ>ⅠandⅣ>Ⅲ>Ⅱ>Ⅰ,respecively.(3)The carbonstrage fthe 3 stands anged in 105.0~199.47 hm2,among which the VF forest had the largest carbon storage,and the PF forest had the smallest carbon storage.The PF forest tree carbon storage was mainly distributed in the trees of diameter class Ⅱ,and the SF forest tree carbon storage was mainly distributed in the diameter class Ⅱ and Ⅳ trees.The VF forest tree carbon storage was mainly distributed in diameter class Ⅳ trees.The results can provide theoretical support for tropical forestry management,forest carbon monitoring and assessment.
