摘要
本文采用树木收获、气体交换等方法,研究了鼎湖山地带性植被季风常绿阔叶林立术第3层和第4层主要优势种云南银柴和柏拉木的生物量和第一性生产力。研究结果表明,云南银柴和柏拉木种群在群落中的生物量分别为干重12009和7874kg·ha^(-1)、鲜重22733和15155kg·ha^(-1);第一性生产力分别为874和480kg·ha^(-1)·yr^(-1)。并对研究结果作进一步讨论,以揭示两种群在群落中的作用和地位。
By methods of field investigation, tree harvesting and gas exchanging, the biomass and primary productivity of Aporosa yunnanensis and Blastus cochinchinensis on Dinghu Mountain are estimated. The biomass of Aporosa yunnanensis is 22733kg·ha^(-1) (fresh weight) or 12009kg·ha^(-1)(dry weight), and that of Blastus cochinchinensis is 15155kg·ha^(-1) (fresh weight) or 7874kg·ha^(-1)(dry weight). The primary productivities of them are respectively 874 and 480kg·ha^(-1)·yr^(-1). After analysing the results, position and role of these two populations in the community are revealed.
