西藏墨脱的植被考察

中国科学院植物研究所生态室高原植被组一行三人,在1973-1976年青藏综合科学考察的基础上,于1980年6至9月再次对东喜马拉雅南坡的墨脱县进行广泛的植被调查。墨脱,藏语是“花”的意思。这不但说明该县自然条件的优越独特,更说明这里植物资源丰富,终年花开不断,十分令人神往。墨脱县境内,北部为东喜马拉雅山和     

著名植物学家王文采

王文采教授是我国杰出的植物学家、中国科学院院士 ,半个多世纪以来 ,在植物分类学和植物地理学研究领域作出了卓越的贡献。王文采先生于 1 92 6年 6月 5日出生于山东济南市 ,祖籍山东掖县 ,1 93 9年从北平厂桥小学毕业后考入北平第四中学。1 94 5年他考入北平师范大学生物系 ,在兼职教授北平研究院林钅容研究员的影响下 ,对植物分类学产生了浓厚的兴趣 ,并下决心把探索生命奥秘作为自己毕生追求的事业。每逢暑假 ,他常独自到郊外爬山涉水 ,采集标本 ,并就地绘出许多植物的外形图和花部构造图。他的才华和献身科学的精神引起时任静生生物调…

Structure and dynamics of subalpine forests in the Wang Lang Natural Reserve, Sichuan, China

Population structure (size, age, spatial patterns) and radial growth patterns are used to analyze regeneration patterns of Abies faxoniana, Betula albosinensis, Betula utilis, Larix potaninii, Picea purpurea, and Sabina saltuaria and reconstruct disturbance history in 8 subalpine forest stands in Wang Lang Natural Reserve, Sichuan, China. In old-growth stands tree regeneration occurs in tree-fall gaps whereby A. faxoniana, Betula sp., P. purpurea, and S. saltuaria persist at stand scales by gap-phase regeneration. Clump sizes of young populations are similar to canopy gap sizes but clumps sizes vary among species. Young Betula patches are larger than those of A. faxoniana suggesting that gap-partitioning by size contributes to species coexistence in mixed stands. Picea purpurea and S. saltuaria are longer lived than A. faxoniana which may compensate for lower recruitment and prevent their replacement by A. faxoniana. Tree regeneration and community structure are also influenced by the understory bamboo Fargesia denudata. Seedlings, saplings, and shrub density all decline with an increase in bamboo cover. Species that regenerate in old-growth forest also regenerate after flooding as do species that establish only on bare substrates (i.e. Larix potaninii, Prunus sp.). Structural and compositional patterns in Wang Lang forests are a reflection of disturbance history, canopy species life history attributes such as dispersal ability, shade tolerance, growth rates, and longevity, and competition of trees and shrubs with understory bamboos.     

Ranunculus ailaoshanicus W. T. Wang,a new species of Ranunculaceae from Yunnan,China

Ranunculus ailaoshanicus W. T. Wang, a new species of the Ranunculaceae from Yunnan, China, is described and illustrated. This species in habit shows striking resemblance to Ranunculus dongrergensis Hand.-Mazz., and differs from the latter in its lower leafless scapes, smaller flowers, and smaller, oblong-elliptic petals with obscure nerves. In R. dongrergensis, the stems are 5–15 cm tall and bear cauline leaves, the flowers are larger, 1–1.8 cm in diam., and the petals are larger, obovate in outline, 4–9 mm long, 2.2–7 mm broad, and nervose.
