天然大节竹林群落林分结构规律的研究

中华大节竹（Indosasasinica）为大中型散生竹类，生长较好的天然竹林主要集中在云南河口大困山海拔400—1000m地区，面积达8580多公顷，具有很高的开发价值。本文根据实测资料，对其林分密度、直径、秆龄、叶面积指数、生物量等因子的变化规律及其相互关系首次进行了系统研究，列出了相应的公式及计量数表。

STUDY ON THE STAND STRUCTURE CHARACTERISTICS OF NATURAL FOREST OF INDOSASA SINICA

Indosasa sinica is a large-middle scattered bamboo which is used for many purposes,and has a highly economical value. It is distrubuted as one kind of natural forests in a large area,or about 8580 ha,on an altitued of 400- 1000m in the Daweishan mountain of Hekou,Yunnan province. In this paper, we have briefly discussed the various stand structure factors, including stand density, average diameter, height, age, leaf area index, biomass,etc,and their relationships also worked out the table of production,management.
