长江口滨海湿地有机碳循环过程及影响因素研究进展
Advances in Organic Carbon Cycle Processes and Influencing Factors of Coastal Wetlands in the Yangtze River Estuary
摘要
Abstract
Coastal wetlands are an important part of the"blue carbon ecosystem".The spatiotemporal distribution and content of soil organic carbon of the coastal wetlands in the Yangtze River Estuary,the carbon sequestration rate,the lateral input and output fluxes of organic carbon and the quantification methods,and organic carbon circulation quantitative analysis model are summarized.The dynamic response of organic carbon storage and composition to different influencing factors is analyzed.It is found that the horizontal distribution of soil organic carbon ranks as Chongxi Wetland>Chongming Dongtan>Jiuduansha>Nanhui tidal flat;Organic carbon flux and concentration changes are mainly affected by water and soil physicochemical properties,terrestrial inputs and tidal dynamic,porewater exchange,human activities and global climate change.In the future,the uniform observation of the soil carbon pools and organic carbon transportation in wetlands of the Yangtze River Estuary should be strengthened,to accurately quantify the contribution of the main factors to organic carbon,which is of great significance to the study of the carbon circulation mechanism and carbon sink assessment of saltmarsh wetlands.关键词
