英文摘要	通过群落调查、异速生长法计算以及样品测定,分别对2010~2011年期间广东湛江高桥红树林生态系统中次生桐花树和原生木榄群落的植物和土壤储量进行了计算,并利用掉落物收集筐对掉落物动态进行了比较研究。研究结果表明,高桥桐花树与木榄群落的植物碳库(以C计,下同)分别为(51.16±12.06)x106g/HM2和(38.52±6.94)x106g/HM2,地上部分明显高于地下部分;土壤碳库分别为(111.86±7.96)x106g/HM2和(106.13±11.12)x106g/HM2,明显高于植物碳库;次生与原生红树林群落的总碳库没有差异(P>0.05)。桐花树和木榄群落的年均掉落物产量分别为556.00 g/M2和971.13 g/M2,均以凋落叶居多,但原生木榄群落的掉落物产量明显高于次生桐花树群落(P<0.001)。由此可见,次生红树林桐花树群落与原生红树林木榄群落的碳储量相当,但均显著低于热带地区的原生红树植物群落。; Carbon pools in both biomass and soil for two dominant mangrove communities( Aegiceras corniculatum and Bruguiera gymnorrhiza) of different succession stages in Gaoqiao,Zhanjiang,Guangdong province,China were quantified using community surveys,allometric calculations and carbon content tests,while litterfall production was also determined during the same period using the litter taps.Our results showed that the carbon pool in plant biomass was( 51.16 ± 12.06) × 106 g C / hm2and( 38.52 ± 6.94) × 106 g C / hm2,respectively,for the A.corniculatum and B.gymnorrhiza communities,with the aboveground biomass significantly larger than the belowground biomass.The soil carbon pool was( 111.86 ± 7.96) × 106 g C / hm2and( 106.13 ± 11.12) × 106 g C / hm2,respectively,for differences in the carbon pools between the secondary and primary mangrove communities( P > 0.05).The mean annual litterfall production for the B.gymnorrhiza community was 971.13 g DW / m2,significantly higher than that of the A.corniculatum community( 556.00 g / m2,P < 0.001).In conclusion,the carbon pools in the secondary A.corniculatum community were comparable with those for the primary B.gymnorrhiza community,but much lower than those for the primary mangrove communities in the tropical regions.; 国家自然科学基金重点项目(30930017); 国家海洋公益性行业科研专项经费项目(200905009;201305021)
