【摘要】 以广西南宁树木园内30年生阿丁枫人工林为研究对象,探究其人工林生物量、生产力、碳储量、年净固碳量及其分配特征。结果表明:阿丁枫地上部分单株生物量为553.60 kg,林分地上部分生物量为271.77 t/hm²,其中乔木层为265.73 t/hm²,占97.78%;地上部分碳储量为125.10 t/hm²,其中乔木层为122.52 t/hm²,占97.94%;各器官碳储量以干材最大,为84.10 t/hm²;林分地上部分生产力为11.32 t/hm²,年净固碳量为5.24 t/hm²,折合CO₂固定量为19.18 t/hm²,可见阿丁枫具有较强的固碳能力,是发展碳汇林的良好树种。更多还原

【Abstract】 The biomass, productivity, carbon storage, annual net carbon sequestration and distribution characteristics of 30-year-old Altingia chinensis plantation in Guangxi Nanning Arboretum were studied. The results showed that the above-ground biomass of Altingia chinensis individual was 553.60 kg and the total biomass of the stand was 271.77 t/hm², of which biomass of arbor layer was 265.73 t/hm², accounting for 97.78%; the above-ground carbon storage was 125.10 t/hm², of which the arbor layer was 122.52 t/hm², accounting for 97.94%; the carbon storage of trunk was the largest, which was 84.10 t/hm²; the above-ground productivity of the stand was 11.32 t/hm², and the annual net carbon fixation was 5.24 t/hm² which converted into CO₂ was 19.18 t/hm². With strong carbon sequestration ability, Altingia chinensis was a good tree species for the development of carbon sequestration forest.更多还原
