西藏色季拉山种子植物垂直带谱的划分与分布特点研究

Study on vertical distributional belts and their floristic characters of seed plants from Shegyla Mountains of Xizang (Tibet), China

将色季拉山种子植物分布划分为山地暖温带针阔混交林带、山地温带针叶林带、亚高山寒温带针叶林带、高山寒带疏林、灌丛、草甸带和高山荒漠带。在上述基础上 ,分析了各带谱的区系组成、性质和特有种分布特点。

Five vertical distributional belts of seed plants from Shegyla Mountains of Xizang(Tibet),China are divided as follows:mountain warm-temperate needle-leave and broad-leave mixed forest zone,mountain temperate needle-leave forest zone,sub-alpine cold-temperate needle-leave forest zone,alpine cold temperate sparse forest,shrub and meadow zone,alpine hungriness zone. Based on above,floristic characters including elements,endemic species of various vertical distributional belts are analyzed.
