摘 要：
为了解白云山森林动态样地植物群落的物种组成、径级结构以及主要物种的空间分布格局,依照BCI(Barro Colorado Island)样地的技术规范,于2015年在白云山国家森林公园建立了一个1 hm2的固定样地,并对样地内胸高直径(DBH)≥1 cm的木本植物进行了全面调查。结果表明:样地共有木本植物61种,隶属于24科38属,总计4 301株,锐齿槲栎(Quercus aliena var.acuteserrata)、华山松(Pinus armandii Franch)、连翘(Forsythia suspensa)和油松(Pinus tabulaeformis Carr)在群落中占主要优势,稀有种占总物种数的12.28%,偶见种占总物种数的47.37%;样地内植物的最大DBH为40.0 cm,平均DBH为7.82 cm;9个被检测的物种都以聚集分布为主,而随着尺度的增大,物种的聚集程度逐渐减弱。研究结果为此区域内植物群落的管理保护积累基础资料和提供技术支持。

摘 要：
To study the composition of species,diameter-class structure and spatial distribution pattern in a dynamic forest community in Baiyun Mountains in accordance with the technical specifications of the BCI( Barro Colorado Island),the author National Forest Park established a permanent plot 1 hm in Baiyun Mountain in 2015,and the woody plants whose diameter at breast height( DBH) are ≥ 1 cm were fully investigated. The results showed that: there are 61 species of woody plants,belonging to38 families and 24 genera,with a total of 4301 strains; Quercus aliena var. acuteserrata,Pinus armandii,Forsythia suspensa and Pinus tabulaeformis in the community are dominant species; rare species and occasional species account for 12. 28% and 47. 37% of the total species respectively; the maximum DBH is 40 cm and the average DBH is 7. 82 cm in the plot; the tested nine species are mainly clustered,and with the increase of scale,the aggregation strength of the species decreases gradually.In short,this study was conducted to understand the species composition of plant communities,diameter-class structure and spatial distribution pattern of main species in the forest dynamic plot of Baiyun Mountain. The results may help to accumulate the basic data and provide technical support for the management and protection of plant communities in the region.
