摘要:
于2017年5-8月对雷公山、高黎贡山和星斗山3个不同纬度自然保护区的秃杉Taiwaniaflousiana群落分别设20 m×50 m样地1个进行对比研究,探讨其动态规律。结果表明,3个保护区的秃杉群落中维管植物共有77科148属243种,其中雷公山的秃杉种群(重要值为0.363 5)占主要优势,其次是高黎贡山,星斗山的秃杉种群处于劣势;多样性优势度(d)指数和丰富度指数(dMa)在乔木层为雷公山大于高黎贡山和星斗山,物种多样性指数(Dr,He'和H2')在乔、灌、草的排序均为:雷公山>高黎贡山>星斗山,3个保护区的秃杉群落均匀度指数(Je)相差不大,都在0.70 ~ 0.95之间。根据吴征镒的中国种子植物属的分布区类型进行进行植物区系分析,3个保护区的秃杉群落的植物区系复杂,划分为24个类型,分布特点以热带分布属为主,温带分布属为辅,世界分布属最少;中国特有2属。
Abstract:
In 2017, one sample plot of 20m × 50m was established respectively at mixed communities of coniferous and broad leaf tree with more distribution of Taiwaniaflousiana in GuizhouLeigongshan National Nature Reserve, Yunnan Gaoligongshan National Nature Reserve and Hubei Xingdoushan Nature Reserve.Investigations were carried out by contiguous grid quadrat method on different layers of the plots and site conditions.The result showed that there were 243 vascular species, belonging to 148 genera and 77 families in 3 plots.T.flousiana population in Leigongshan was dominated with importance value of 0.363 5, followed by Gaoligongshan and Xingdoushan.The dominance index and species richness index at arbor layer in Leigongshan was higher than that in the other two reserves, species diversity index at arbor, shrub and herb layer was ordered by Leigongshan>Gaoligongshan>Xingdoushan.The species evenness index in different communities of 3 reserves was similar, ranging from 0.7 to 0.95.Analysis on areal-types of genera of plant in T.cryptomerioi des communities in Leigongshan, Gaoligongshan and Xingdoushan demonstrated that it could be divided into 24 types, dominated by tropical distribution, followed by temperate one, and wide spread was the last, 2 genera was endemic to China.
