摘　　要：湿地生态系统是地球主要生态系统之一,其有机碳储量及碳循环是全球碳循环研究的重要基础,也是全球气候变化研究的重要内容之一。研究表明:湿地保护和恢复能促进碳积累和减少温室气体排放。笔者探讨了湿地生态系统碳储量、碳平衡和温室气体排放的影响、湿地与全球气候变化关系等方面的问题,并对洞庭湖湿地碳循环研究做了展望。Wetland ecosystem is one of three important ecosystem-types on the earth. To understand well the organic carbon accumulation mechanism and its cycling characteristics is the very basis and one of the most crucial research contents of global carbon cycling and global climate change. Some researches showed that wetland ecosystem protection and restoration are helpful to carbon accumulation and greenhouse gases reduction, which to some extent can mitigate the negative effects of climate change. The paper put its emphasis on several closely interrelated issues, including wetland carbon stock, carbon balance and the effects of greenhouse gases emission, the relations between wetland ecosystem and global climate change, as well as an outlook of carbon cycle of the Dongting Lake wetland ecosystem.
