| 摘要: |
| 广东是我国红树林分布面积最大的省份，其红树林碳储量对于我国红树林管理及政策制定具有重要的指导意义。本研究结合实地调查数据、已发表文献数据及第三次全国国土调查数据，估算了广东红树林生态系统碳储量并分析其影响因素。调查结果表明广东红树林生态系统总碳储量为2 845.99 kt C，其中植被碳储量为940.10 kt C，占生态系统总碳储量的33.03%；土壤碳储量为1 905.89 kt C，占比66.97%。广东红树林碳储量主要集中在湛江、江门、阳江、珠海等红树林面积分布较大的地市。广东红树林碳密度平均值为291.53 t C/hm2，低于低纬度的海南以及全球红树林碳密度平均值，但高于广西、浙江及福建。此外，广东不同红树群落土壤碳密度具有明显差异，土壤碳储量整体呈现出红海榄+木榄(Rhizophora stylosa+Bruguiear gymnorrhiza)>无瓣海桑(Sonneratia apetala)>白骨壤(Avicennia marina)>木榄(B.gymnorrhiza)>秋茄(Kandelia obovata)>桐花树(Aegiceras corniculatum)特征。整体来看，红树林生态系统具有较高的储碳能力，增加红树林面积可以显著促进红树林碳储量增长。本研究结果可为广东碳汇核算提供关键的本底数据与计量参数，从而服务于温室气体清单编制与碳中和目标分解。 |

| Abstract: |
| Guangdong is the province with the largest area of mangroves in China,and its mangrove carbon stock has significant implications for mangrove management and policy-making in China.This study combined field survey data,published literature data,and the data from the Third National Land Survey to estimate the carbon stock of the mangrove ecosystems in Guangdong,and analyzed the influencing factors.The results indicated that the total carbon stock of mangrove ecosystems in Guangdong was 2 845.99 kt C,in which vegetation carbon stock (940.10 kt C) accounted for 33.03%,while the soil carbon stock was 1 905.89 kt C,accounting for 66.97%.The carbon stock was mainly concentrated in the cities with a large area of mangroves,such as Zhanjiang,Jiangmen,Yangjiang,and Zhuhai.The average carbon density of mangrove ecosystems in Guangdong was 291.53 t C/hm2,which was lower than that in Hainan at a lower latitude and the global average value,but higher than that in Guangxi,Zhejiang,and Fujian.In addition,there were significant differences in soil carbon density among various mangrove communities in Guangdong,and the soil carbon stock showed the trend of Rhizophora stylosa+Bruguiera gymnorhiza>Sonneratia apetala>Avicennia marina>B.gymnorhiza>Kandelia obovata>Aegiceras corniculatum.Overall,the mangrove ecosystems have a high carbon storage capacity and increasing the mangrove area can significantly promote the growth of mangrove carbon stock.The study result can provide key background data and measurement parameters for carbon accounting in Guangdong,and serve the compilation of greenhouse gas inventories and the decomposition of the carbon neutrality goal. |
