摘要
通过对云南省香格里拉县植被的调查,统计到香格里拉县有种子植物159科705属2 267种(包括变种、亚种和多年栽培种)。种子植物分布区类型组成是温带起源的科占48.5%,温带分布属占66.05%,其中以北温带分布属最多,占28.99%,其次是东亚分布属,占14.47%。分布区类型分析表明,香格里拉县植物区系具有温带区系的特点,属于中国喜马拉雅植物区系中横断山脉地区。此区系具有亚热带北缘的性质,古特有种丰富。
There are 159 families, 705 genera, and 2 267 species (including varieties, subspecies and cultivated species) in Xianggelila County, including 28 genera which are endemic to China. In the floristic composition of the forest, the temperate families make up 48.5 % of the total families, the temperate genera take up 66.05 % of total genera. So the flora has some obviously temperate characteristics, and is a part of Hengduan Mountains region of Sino-Himalaya flora, occurred at the northern margin of subtropics. [Ch, 4 tab. 16 ref. ]
