四川稻城亚丁自然保护区主要植被类型

Main Vegetation Types in Yading Nature Reserve,Daocheng County, Sichuan Province

亚丁自然保护区位于青藏高原东南缘,横断山脉之东侧,地形复杂,气候多样,是一个特殊的生态地理区域,植物资源十分丰富,构成了复杂多样的植被类型。按照四川自然植被分类的依据、原则和系统,根据植物群落的种类组成、群落结构、群落外貌、动态和生态地理分布等进行合理的分类,以探索该区域植被的发生、发展和演替规律,进一步提高植被的生产能力。

Yading Nature Reserve is located in the southeastern margin of the Qinghai -Tibet Plateau anu the east of Hengduan Mountains with complicated topography and climates, which is a special eco-geo- graphical region having abundant plant resources to constitute complex and varied vegetation types. Based on the classification, principle and system of natural vegetation in Sichuan, and the species composition, community structure, community appearance, dynamic and ecological geographic distribution of plant communities, discussion is made on the occurrence, development and movement pattern of the vegetation types in this region, aiming at further improving the production capacity of the vegetation.
