西双版纳竹类地理分布及类型的初步研究

西双版纳是中国乃至世界上竹类植物资源最为丰富的地区之一。研究结果表明，西双版纳的竹类根据其分布特性可分为三类，即（１）热带竹类，（２）南亚热带竹类，（３）山地温带竹类。而从区域地理分布区来看，根据中国植物区系分布区类型的划分标准．则可将西双版纳竹类划分为五个分布区类型，即（１）泛热带分布类型，（２）热带亚洲至热带非洲分布类型．（３）热带亚洲（印度—马来西亚）分布类型，（４）东亚分布类型，（５）中亚分布类型（喜马拉雅和我国西南分布亚类型）。文章还对西双版纳现存主要的天然竹林群落的分布及生境以及主要的栽培种及竹状况进行了探讨。

A PRELIMINARY STUDY ON GEOGRAPHICAL DISTRIBUTION AND TYPES OF BAMBOO FOREST IN XISHUANGBANNA,YUNNAN, CHINA

Xishuangbanna is one of the richest areas of bamboo resources in China and the world. According to the distributive characters of bamboo in Xishuangbanna,the bamboos grown here fall roughly into three categories: 1) Tropical bamboo;2) Southern subtropical bamboo; 3) Mountain temperate bamboo, If we based on the opinion of Prof. Wu Zhengyi (C. Y. Wu), all of them can be classified into 5 areal types as follows: 1) Pantropic; 2) Trop. Asia to Trop. Africa; 3) Trop. Asal (Indo Malesia): 4) E. Asia: 5) C. Asia (Subtype of Himalaya et S. W. China). In this paper, the authors also approach the distributive characteristics and environment of natural bamboo forest and cultivated bamboo forest.
