对西溪湿地3个样带中植物群落生物量和有机碳含量的季节动态进行了研究，同时分析了3个样带植物群落有机碳的积累量．结果表明：植物从春季（4月）进入生长季后，其地上生物量逐渐增加，10月份达到最大，表现为芦苇带＞芦苇混交带＞香蒲带，地下生物量也呈增加趋势．3个样带中植物各器官有机碳含量差异极显著，并表现出季节变化特征，叶片有机碳含量在7月达到最大，芦苇混交带和芦苇带植物茎有机碳含量在10月达到峰值．3个样带植物各器官有机碳积累量不同，表现为芦苇带＞香蒲带＞芦苇混交带．可见，芦苇群落是西溪湿地固碳的主要功能植被类型，同国内其它湿地相比，西溪湿地的固碳潜力巨大．

The seasonal dynamics of biomass and organic carbon content as well as organic carbon accumulation in the three plant communities in Xixi wetland are studied in the paper .The results show that plant biomass gradually increases since spring ,and reaches the peak in October . The aboveground biomass is ranked in decreasing order as Phragmites australis zone > Phragmites australis mixed zone> Typha orientalis zone ,the underground biomass also increases .The organic carbon content in different organs of the three communities shows the remarked difference (P<0 .01) and seasonal changes .The organic carbon content in the leaves of the three communities reaches the peak in July ,while the organic carbon content in the stems of Phragmites australis zone and Phragmites australis mixed zone reaches the peak in October . The organic carbon accumulation is ranked in decreasing order as Phragmites australis zone> Typha orientalis zone>Phragmites australis mixed zone .The paper suggests Phragmites australis community is the main functional plant for carbon storage in Xixi wetland ,and there is a huge potential for carbon storage in Xixi wetland .
