摘  要：
为研究宝天曼森林生物多样性及物种分布规律,取1hm2宝天曼杂木林作为试验样地。对样地的木本植物物种组成、区系特征、径级结构和空间分布格局等进行了分析,结果表明:样地内胸径≥1cm的木本植物共有31科57属95种,计2 323株;属的温带区系成分占总种数的81.05%,热带区系成分占17.89%;木本植物整体径级结构呈明显的倒"J"型,4种优势植物中绝对优势种锐齿槲栎呈"双峰"型,说明群落总体结构稳定、更新良好;锐齿槲栎整体上聚集分布不明显,水榆花楸聚集分布明显,三桠乌药和青楷槭呈一定程度的聚集分布。宝天曼杂木林样地的物种组成较为丰富、群落比较成熟,符合南暖温带-北亚热带过渡地带的植被特征。

摘  要：
To study the biodiversity and species distribution of woody plants in Baotianman national nature reserve,the species composition,flora characteristics,diameter level structure and spatial distribution pattern were analyzed in one ha Baotianman shaw.The results showed that there were 2 323woody plants with diameter at breast height≥1cm,belonging to 95species,57 genera and 31families;the study of flora revealed the vegetation characteristics of transitional zone between warm temperate zone and north subtropical zone with more temperate elements(81.05%in total)and less tropical ones(17.89% in total);the size distribution of all trees followed a reverse"J"shape,while Quercus aliena as the absolute advantage dominant plant of the four advantage dominant plants showed bimodal type,which indicated that the community structure was stable and naturally regenerated well;the spatial distribution pattern was remarkably aggregated in Sorbus alnifolia,was aggregated to some degree in Lindera obtusiloba and Acer tegmentosum,and was not aggregated in Quercus aliena.The species composition of Baotianman national nature reserve shaw was abundant,and the community was mature,which was coincident with the vegetation characteristics of transitional zone between warm temperate zone and north subtropical zone.
