摘要
在对九寨沟国家级自然保护区历时2 a的详细调查和大量标本采集、鉴定的基础上,对区内菊科植物的属、种组成、分布区类型、区系特征等进行了统计和分析。结果表明:1.保护区内共有58属219种菊科植物;2.优势属较为明显;3.具有明显的温带性质;4.区系成分复杂;5.中国特有分布种以风毛菊属植物为主。
In a two-year survey carried out in Jiuzhaigou Valley Natural Reserve, a great number of plant specimens were collected and identified. Fifty-eight genera with 219 species of the family Compositae were identified in the reserve. The dominant genera seemed rela- tively prominent and showed an obvious feature characteristic of the temperate zone. The composition of the flora appeared quite complicated. Most of the species endemic to China fell into the genus Saussurea.
