摘要
从地上、地下有机物质生产对湿地碳输入的贡献,湿地土壤碳库以及土地利用变化对湿地土壤碳库和碳排放的影响,甲烷排放和可溶性有机碳输出以及影响因子,湿地生态系统碳循环动态模型4个方面对湿地生态系统碳循环国内外研究进展和研究成果进行综述、分析,提出了我国亚热带区域天然湿地碳循环研究的主要热点和方向:(1)沿海湿地碳库估算及土地利用转化对土壤碳库和温室气体排放的影响;(2)酸沉降对于我国东南沿海低纬度地区湿地甲炕排放的影响;(3)沿海湿地生态系统碳循环动态模型的应用与开发;(4)湿地系统可溶性有机碳的输出机理探讨.
Carbon cycling in wetlands ceosystem is a key field of the studies on global carbon cycling and wetland sciences. The contributions of both aboveground and belowground organic production to the input into wetland's soil carbon pool, the impacts of land use transformation on soil carbon storage and carbon flux, the methane emission and dissolved organic carbon losses together with influencing factors, and wetland's carbon eycling model were reviewed and analysed. Future priorities on studies of carbon balance in the wetlands in the subtropical region aloe recommended to: (1)measure the carbon storage and methane fluxes in the costal wetlands; (2)analyse the impacts of sulfate deposition on methane emission from coastal wetland in Southeast region in China; (3)develop wetland carbon cycling model, and (4)explore the mechanism for output of dissolve organic carbon from wetland system.
