摘　　要：为探索南昆山自然保护区森林群落的物种组成和结构,利用样方调查法调查样地内胸径≥1 cm的木本植物,分析其群落树种组成、树种多度分布格局和径级结构。结果表明,样地内胸径≥1 cm的木本植物共有2576株,隶属35科60属98种,樟科、壳斗科和茜草科等6个优势科共有22属53种,华润楠、鸭公树和硬壳柯是优势树种;样地内稀有种16种,偶见种37种;树木径级遵从倒“J”形分布。表明该群落结构总体稳定,树木生长健康,样地没有明显的断层现象,群落总体上更新良好。研究结果为了解研究区森林生态系统和保护其生物多样性提供参考。To explore the characteristics of forest community species composition and structure in the Nankunshan Nature Reserve,the sample plot survey method was used to investigate all woody plants with a breast height diameter≥1 cm in the sample plot,and their community tree species composition,distribution pattern of tree species abundance and diameter class structure were analyzed.The results showed that there were a total of 2576 woody plants with a breast height diameter of≥1 cm in the sample plot,belonging to 35 families,60 genera and 98 species.There were 22 genera and 53 species in 6 dominant families including Lauraceae,Fagaceae and Rubiaceae.Machilus chinensis,Neolitsea chui and Lithocarpus hancei were the dominant tree species;There were 16 rare species and 37 occasional species in the sample plot;Tree diameter class followed an inverted“J”shape distribution.This indicated that the overall structure of the community was stable,the growth status of trees was healthy,there were no obvious faults in the plot,and the community was generally well updated.The research results provided references for understanding the forest ecosystem and protecting its biodiversity in the study area.
