| 中文摘要: |
| 深化对不同城市森林类型碳储量和碳汇潜力的认识是建设低碳森林城市的重要环节。基于生物量调查，对来宾市城郊区32年生的阴香人工林生态系统的碳储量及分配格局进行了研究。结果表明，阴香人工林乔木层各器官的平均碳含量为508.70g/kg，各器官碳素含量介于493.5~511.5 g/kg之间，大小排序为中根>根兜>树叶>树干>大根>细根>皮>大枝>枯枝>小枝。阴香人工林生态系统总碳储量为370.97 t/hm2，其中阴香人工林乔木层碳储量为233.05 t/hm2，表明该生态系统主要碳库集中在乔木层，与其冠幅大、枝繁叶茂的林分发育特征密不可分。 |

| The understanding of carbon storage and sequestration potential in various city forest types was an important work in the construction of low carbon forest city. Based on the investigation of biomass, carbon storage and distribution pattern of 32-year -old Cinnamomum burmanni plantation ecosystem was studied in the suburb of Laibin city, Guangxi province. The results showed that the
average carbon content in different organs of C. burmannii plantation tree layer was 508.70 g/kg, ranged from 493.5 g/kg to 511.5 g/kg, with the order of middle root > root tip > leaf > trunk > coarse root > fine root > bark > coarse branch > dead branch > branchlets. The total carbon storage in C. burmanni plantation ecosystem was 370.97 t/hm2, of which the tree layer was 233.05 t/hm2, which indicated that the major carbon pool located on the tree layer, being related with the luxuriant foliage of the stand development characteristics. |
