摘要
应用法瑞地植物学派的理论和方法,将云南潞江坝1300m以下地区干热河谷植被确定为1群目、3群属、6群丛、4亚群丛。通过对植被外貌、结构、区系组成、分布特点的分析,认为本区现存植被主要由河谷季雨林长期破坏所至,目前较典型的干热河谷灌草丛植被类型属于次生性稀树草原或半自然性稀树草原。
By means of the theory and method of French-Swiss phytosociolo-gical school, the vegetation of Nujiang dry-hot river valley below 1300m inLujiangba of Yunnan have been classified into one order, three alliances, six associ-ations and four subassociations; through the analyses of physiognomy, structure,floristic composition, ecological environment and distribution of the vegetation, weconsider that the most of them were mainly resulted in a longterm destruction ofthe river valley monsoon forest, and the typical vegetation types may be regardedas secondary savannas or semi-natural savannas.
