| Abstract: | The woody plant group in Wolong region were not only investigated in datail, the research data in or of the past and now were but also collected, counted and analysised. The results have shown that there were 83 families, 224 genera, 684 species (incuding in fraspecific taxon and not incuding cultivar) of woody plants at Wolong region. The flora analysis inclicated that the temperate zone elements were dominate 58.33% of the whole genera and the tropical elements took 36.56%. The rare and endangered plants, the genera of simple species and the minor species, and the Chinese endemic genera occupied a large propertion. This reflected the ancient characteristics of the historical origin of the species at the region. There were the complicacy, extensive contact, and alternate distribution of every kind of geographic elements at the region, and it is a specific to extend the cold-resistant species of tropical, subtropical elements and the Southwest Chinese endemic elements, all above provide engough supports for the viewpoint that the alpine temperate elements of the tropical, subtropical region in Eurasia originate in West Sichuan Mountains. |
