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/hm^(2),其中乔木层为265.73 t/hm^(2),占97.78%;地上部分碳储量为125.10 t/hm^(2),其中乔木层为122.52 t/hm^(2),占97.94%;各器官碳储量以干材最大,为84.10 t/hm^(2);林分地上部分生产力为11.32 t/hm^(2),年净固碳量为5.24 t/hm^(2),折合CO_(2)固定量为19.18 t/hm^(2),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。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/hm^(2),of which biomass of arbor layer was 265.73 t/hm^(2),accounting for 97.78%;the above-ground carbon storage was 125.10 t/hm^(2),of which the arbor layer was 122.52 t/hm^(2),accounting for 97.94%;the carbon storage of trunk was the largest,which was 84.10 t/hm^(2);the above-ground productivity of the stand was 11.32 t/hm^(2),and the annual net carbon fixation was 5.24 t/hm^(2) which converted into CO_(2) was 19.18 t/hm^(2).With strong carbon sequestration ability,Altingia chinensis was a good tree species for the development of carbon sequestration forest.
