摘    要:为了研究云南热区几种主要阔叶人工林分的固碳能力,利用实际测定生物量的方法对西双版纳的几种阔叶人工林生态系统的C储量进行了研究。研究结果发现,山桂花纯林,西南桦纯林,高阿丁枫纯林,马尖相思纯林以及西南桦+山桂花混交林和西南桦+马尖相思混交林几种7年生人工林生态系统的C密度为109.37~136.97 t/hm2。几种人工林分的年固C量在3.97~7.03 t/hm2·a之间。表明:这些树种都是开展以固C为目标的生态造林项目的适合树种。

关 键 词:云南热区  阔叶人工林  C密度  年固C量

Abstract:In order to test the potential of carbon sequestration for plantations of hardwood species in tropical and subtropical Yunnan,carbon stock and rate of sequestration of six kinds of hardwood plantations were assessed through direct biomass measurement. Research results showed that carbon densities ranged from 109. 37 t/hm2 to 136. 97 t/hm2 for 7 years old plantations of Paramichelia baillonii ,Belula atnoides, Altingia excelsa, Acacia mangium and mixing Betula alnoides with Paramichelia baillonii, mixing Betula alnoides with Acacia mangium. Their annual rates of carbon sequestration were tested with a range from 3. 97 t/hm2 · a to 7. 03 t/hm2·a, which indicated these species could be good choices for carbon offsetting projects in tropical and subtropical Yunnan.
Keywords:tropical and subtropical Yunnan  hardwood plantation  carbon density  annual rate of carbon sequestration
