以福建九龙江口24年生、48年生的秋茄红树林为研究对象，通过测定秋茄林木层各器官、凋落物层、土壤层含碳率和土壤呼吸，结合各组分生物量和年净生产量，计算秋茄红树林的碳储量和年净固碳量。结果表明：24年生、48年生秋茄林碳储量分别为183.31、244.45 t · hm-2，其中林木层碳储量分别为162.45、222.95 t · hm-2，凋落物层碳储量分别为15.05、16.99 t· hm-2，土壤层和林木层碳储量在生态系统碳储量中的比例均随林龄增大而升高。24年生、48年生秋茄林均表现出了碳汇功能，其中24年生秋茄林年净固碳量较大，为18.51 t· hm-2· a-1；而48年生秋茄林的碳汇功能较低，为7.01 t· hm-2· a-1。

The 24 and 48 years old of Kandelia candel mangroves were studied in Jiulongjiang Estuary.The carbon content of organs and soil in tree,litterfall,soil layers and soil respiration was measured ,and then carbon storage and net carbon sequesation were cal-culated by carbon content and soil breath as well as biomass or net productivity of plantations .The carbon storage were 183.31 and 244.45 t· hm-2 in 24 and 48 years old of K.candel mangrove forest ,respectively.The carbon storage of tree layer in 24 and 48 years old of K.candel mangrove forest were 162.45 and 222.95 t · hm-2 , respectively.The carbon storage were 15.05 and 16.99 t · hm-2 ,respectively.The proportion of tree layer and soil carbon storage in ecological system carbon storage increased with forest a -ges.The net amount of carbon storage of 24-yr-old K.candel mangrove forest (18.51 t· hm-2 · a-1 ) was higher than that of 48-yr-old K.candel mangrove forest (7.01 t· hm-2 · a-1 ).
