| 摘要: |
| 马尾松(Pinus massoniana)林是中国东南部湿润亚热带地区分布最广的针叶林类型，但目前对其群落组成、类型及结构的认知仍然有限。本研究基于广西区内以马尾松为优势种的群落的野外实地调查数据，依据《中国植被志》研编标准、规范和方法，对133个样方进行数量分类与特征分析，划分出群丛组和群丛，并系统描述各群丛组的物种组成与群落结构。主要结果如下：(1)共记录维管植物566种，隶属110科300属，种类最多的是樟科(Lauraceae，40种)，其后为大戟科(Euphorbiaceae，35种)、禾本科(Poaceae，32种)和茜草科(Rubiaceae，30种)，单种科达41科；(2)区系地理成分以热带分布区类型占优，与广西暖热性气候条件相符；(3)生活型组成上，木本植物占优势(76.0%)，远高于草本植物(24.0%)，而且常绿种类占比明显高于落叶种类；(4)依据植被分类体系，将133个样方划分为16个群丛组和42个群丛，揭示了马尾松林在广西区内丰富的群落类型与结构分化。综上，本研究细化了广西马尾松林的群落分类，明确了其物种组成与区系特征，为该区域马尾松林的生物多样性保育、可持续经营及植被恢复提供了基础数据和科学支撑。 |

| Abstract: |
| Pinus massoniana forests represent the most widely distributed coniferous forest type in the humid subtropical zone of southeastern China.However,systematic knowledge regarding their community composition,classification,and structural characteristics remains limited.On the basis of field survey data from communities dominated by P.massoniana in Guangxi and following the standards and protocols for the compilation of the Vegetation of China,quantitative classification and characteristic analysis were carried out for 133 plots.The associations and association groups were delineated,and their species composition and community structure were systematically detailed.The main results are as follows:(1) A total of 566 vascular plant species were recorded,belonging to 300 genera of 110 families.The most species-rich family was Lauraceae (40 species),followed by Euphorbiaceae (35 species),Poaceae (32 species),and Rubiaceae (30 species),with 41 families represented by a single species.(2) The floristic geographical elements were predominantly tropical,consistent with the warm and humid climatic conditions of Guangxi.(3) In terms of life forms,woody plants were dominant (76.0%),substantially exceeding herbaceous plants (24.0%).The proportion of evergreen species was significantly higher than that of deciduous species.(4) According to the vegetation classification system,the 133 plots were classified into 16 association groups and 42 associations,revealing high diversity of community types and structural differentiation of P.massoniana forests in Guangxi.In conclusion,this study refines the community classification of P.massoniana forests in Guangxi and clarifies their species composition and floristic characteristics.The findings provide foundational data and scientific support for biodiversity conservation,sustainable management,and vegetation restoration of P.massoniana forests in the region. |
