摘要:

通过对苍山种子植物164科,852属,2503种,45亚种,194变种在各个层次不同角度上的分析,探讨了本区种子植物区系的性质、地位、起源及演化。区系分析表明:大理苍山种子植物区系在我国区系区划上属于东亚植物区,中国-喜马拉雅森林植物亚区,横断山脉地区,三江峡谷亚地区;其区系具有鲜明的温带性质;现代苍山植物区系是在印度板块与欧亚板块碰撞,古地中海退却和喜马拉雅隆升等地质事件背景下,由古地中海成分、北极—第三纪成分及古南大陆成分融汇发展而来;苍山的特有现象较为显著,新老皆备,且以新特有成分为主,它既是古特有成分的避难所,也是新特有成分发展的温床;苍山在植物分布上是呼应东、西、南、北的纽带,同时又是很多成分分布的边界,是重要的区系节。

Abstract:

The floristic characteristic, position in Chinese floristic division, and the origin and development of the flora of the Cangshan Mountain Range (the Dali Range) were discussed from different aspects, based on the local seed plants of 2503 species, 45 subspecies, 194 varieties, belong to 852 genera in 164 families. Preliminary conclusions are as follows: The Cangshan Mountain Range belongs to three rivergorges subregion, Hengduan mountain region, SinoHimalayan forest subkingdom, East Asiatic Kingdom, in Chinese floristic division. The floristic characteristic of seed plants of the Cangshan Mountain Range is temperate. Because of the geological events of the collision between Eurasian Plate and Indic Plate, the Tethys fading away, and the uplift of Himalayas, the elements from Gondwana land, Mediterranean and ArcticTertiary gradually developed into its modern flora. The endemism within the flora is rich, with the neoendemic elements dominant. It shows that the Cangshan Mountain Range is not only a refuge for some ancient floristic elements but also a differentiation center for young floristic elements. It is an important floristic spot connecting floristic elements from different directions. And the distribution limits of a great deal of elements also are here.
