摘要
本文采用维量分析以估测滇西南季风常绿阔叶林短刺栲群落的净第一性生产量.结果表明,12年生幼龄林具有较高的净生产量,比42年生中龄林高253.1g/m^2·a.幼龄林的净第一性生产量为2259.5g/m^2·a,其中树占31.47％,枝占20.85％,叶占20.42％,根占25.91％,草食动物的叶采食量占1.35％.中龄林的净第一性生产量为2006.4g/m^2·a,其中树干占36.01％,林占21.63％,叶占19.03％,根占21.53％,叶被采食量占1.80％.
The dimension analysis was used to estimate the net primary production for Castanopsis echidnocarpa community of monsoon evergreen broad-leaved forest in southwest Yunnan. The net primary production in 12-year-old stand was 253. lg / m2·a highter than in 12-year-old stand.
The net primary production in 12-year-old stand is 2259.5 g/ m2· a. of which 31.47% is stems 20.85% branches, 20.42% leaves, 25.91% roots, and 135% leave biomass grazed by in sects and herbivorous. The net primary production in 42-year-old stand is 2006.4 g/ m2 ·a, of which 36.01% is stems, 21.63% branches, 19.03% leaves, 21.53% roots, and 1.80% leave biomass by insects and herbivorous.
