西双版纳热带雨林植物区系组成初步分析

作者1958—1979年在中国科学院云南热带森林生物地理群落站工作期间,选取了三个代表西双版纳热带森林的林地,用植物群落学样方法做了大小不等的11个样地,共计15700m~2(1.57公顷)。根据这些样地资料研究讨论了在一定面积上西双版纳热带雨林区系组成,区系成分在群落中的垂直配置,森林的热带性程度以及与邻近地区森林区系的关系。同时比较了西双版纳雨林与滇东南、滇西南雨林的性质及其在东南亚雨林群系中的地位。

A PRELIMINARY ANALYSIS ON THE FLORA COMPOSITION OF TROPICAL RAIN FOREST IN XISHUANGBANNA OF SOUTHERN YUNNAN

During the 1958-1979 years, at the Yunnan Biogeocoenological Station of Tropical Forest, the writer made a survey of the flora of tropical rain forest by the quadrat method of phytococnology in Xishuangbanna of the southern Yunnan. Through putting to order the recent materials, the species cormophytes (including bryophytes, pteridophytes, gymnosperms and angiosperms) have reached a total of 364 in the area of 1.57 ha, distributed among 121 families. According to the inve tigation and data, the writer dicusece the floristic compo ition of rain forget, the dipo ition of floritic elements in vertical tru-cture and its relationship with the flora of neighboring distriets. Besides, work have been done in the comparative tudy on the flora of tropical rain foregt in Xinhuangbanna of the outhern Yunnan of both the sou-theastern and the southwe tern, and their status. in the souhteastern Asia rain forest formation.
