摘要: 本文采用空间代替时间的方法组建了我国热带雨林的重要优势种望天树(Parashorea chi-nensis)种群的静态生命表,并建立了种群结构动态模型,种群材积动态模型和种群自疏模型。结果表明望天树种群现阶段是稳定型种群,具不断扩大的潜力;种群材积约170年前符合logistic增长,170年后材积下降;种群的自疏指数约为-2.1。

关键词: 望天树, 种群动态, 静态生命表

Abstract: The use of the difference of space distribution stand for the progress of time set up the static life-tablp of Parashorea chinensis population, which is a main dominant and rare species of tropical seasonal rain forest, in Bubeng region situated in the south of Yunnan Province (21'25/-21'8/N, 101'4/-101'2/E).

Key words: Parashorea chinensis
