| 研究52 个乔木树种纯林的碳储量，分析其固碳能力差异，为碳汇造林选用乔木树种提供参考
依据。以广东省东江林场11 年生的乔木树种试验林为研究对象，测定52 个树种生长量和树干、树枝和
树叶的含碳率。按照平均木法，算出平均木生物量，结合平均含碳率、林分密度与保存率，估算碳储量。
结果表明，不同树种林分碳储量差异极大，最高碳储量（厚荚相思Acacia farnesiana）比最低碳储量（紫
玉兰Magnolia liliiflora）相差约20 倍，年均碳储量在10 t/hm2 以上的树种有含羞草科的厚荚相思、大叶
相思A. auriculiformis 等5 个树种，年均碳储量在5~10 t/hm2 的有灰木莲Manglietia glanca、红荷Schima
wallichii 等18 个树种。以保存率和单位面积碳储量2 个主要性状作聚类分析，可将52 个树种按固碳能力
划分成4 种类型的碳汇树种。 |

| Abstract: |
| Pure forest carbon storage of 52 tree species were studied and their carbon sink capacity differences
were analyzed to provide a reference for the selection of tree species for carbon sink afforestation. Taking 11-year-old
tree species experimental forest in Dongjiang Forest Farm of Guangdong province as the research object, the
growth, the carbon content of trunk, branches and leaves, water content , wood basic density of 52 tree species were
measured. According to mean sample-tree method, the mean sample-tree of each tree species was obtained first,
and then the mean sample-tree biomass was estimated by the general biomass model of the whole tree. The average
carbon content of tree species was calculated by the weighted method. Finally, the carbon storage of 52 tree species
pure forest were estimated by combining afforestation density with survival rate. The results showed that there were
great differences in carbon storage among tree species. The highest carbon storage tree species (Acacia farnesiana)was about 20 times higher than the lowest carbon storage tree species (Magnolia liliiflora). Average annual carbon
storage of pure forest more than 10 t/ha was Acacia farnesiana and Acacia auriculiformis etc. There were 18 species
including such as Manglietia glanca, Schima wallichii,etc. with an average annual carbon storage of 5-10 t/hm2.
52 tree species could be classified into 4 types of carbon tree species according to their carbon sequestration capacity
and preservation rate. |
