摘要
采用法瑞植物社会学学派的排表法对巧家干热河谷的植被进行系统分类,并以数量分类方法(组平均法)进行验证,结果将当地植被划分为一个群目(order)、两个群属(alliance)、四个群丛(association)。本文还详细探讨了当地植被的生境及区系、生态学特征,同时对比了当地植被与元谋干热河谷植被的异同。
To have classified the vegetation in Qiaojia dry -hot river valley of Jinsha River in Yunnan systematically by the method of French-Swiss phylosocio-logical school, we have got a result that the local vegetation is composed of one, order, two alliances, four associations hierarchically.
Dodonaeo-Heleropogonetalia contorti I . Phyllantho-Heleropogonion contorti
1. Barlerio-Hetcropogonctum contorti
2. Arthracio-Coriarictum nepalensis
3. Calotropetum giganteac I . Opuntion monacanthae
4. Sclaginllo-Opuntictum monacanthac
This result has been verified by the method of hierarchical agglomcrativc classification (Group-average). We have described environmental, floral and ecological characters of the local vegetation minutely in this paper. A vegctational comparison between Qiaojia and Yuanmou dry-hot river valleys has been also given here.
