中文摘要：

对红树林自然分布区域北缘区不同起源（天然林和人工林）秋茄林湿地生态系统的碳储量及分配格局进行对比分析。结果表明：（1）秋茄天然林生态系统碳储量（乔木层＋林下植被＋死地被物＋土壤碳）约为221.8 t/hm2,人工林约为154.6 t/hm2,秋茄天然林生态系统在碳汇功能上优于人工林;（2）无论天然林还是人工林生态系统,土壤是主要碳库,分别占总碳储量87.0%和93.5%;乔木层碳储量次之（天然林12.8%;人工林6.5%）,林下植被和死地被物对生态系统碳储量贡献微小,仅0.01%～0.12%;（3）与林外土壤碳库相比,红树林湿地碳库更具优势。

英文摘要：

The carbon storage an d carbon allocation patterns of natural and artificial Kandelia candel wetland ecosystem were investigated in north marginal region of mangrove.The results were as follows：（1）The ecosystem’s carbon stock（tree layer＋understory＋litter floor＋soil）was about 221.8 t/hm in the K.candel natural forests,while that of the plantations was 154.6 t/hm2.We primarily concluded that the carbon stock in the natural forests was higher than that in the plantations;（2）The carbon pool in the soil was the main resource of ecosystem’s carbon storage of both K.candel natural forests and plantations,whose respective amounts were 87.0% and 93.5%.The carbon stock of tree layer was on the second place（natural forests： 12.8%;plantations： 6.5%）and the least contribution to the stock of carbon was attributed to the understory and litter floor,which was only 0.01% to 0.12%;（3）Compared with the soil carbon pools outside the forest,the superiority of wetland ecosystem of K.candel mangrove is obvious.
