%X 碳循环是地球上最重要的生物地球化学循环之一，它广泛参与地表系统其它物质交换，并深刻影响着人类的生存环境。对于近些年来大气中出现的碳源与碳汇收支不平衡问题，导致碳失汇的发生。湿地生态系统碳循环是地球碳循环系统的重要组成部分，对于实现碳中和具有重要的生态价值。造成碳失汇的原因众多，包括气候变化、CO<sub>2</sub>施肥作用、氮沉降增加、土地利用方式改变等。湿地是四大陆地生态系统之一，深入了解湿地碳储量状况及碳循环过程是研究全球碳循环的重要基础，也是全球气候变化研究的重要内容之一。基于碳达峰、碳中和战略目标，面对碳失汇的严峻挑战，加强湿地科学研究，以增加湿地面积，提高其自然恢复能力，增强现有湿地生态系统服务功能，探讨湿地生态系统碳盈亏关系，挖掘自然湿地的低碳汇价值，实现碳中和，制定合理的湿地恢复政策，对于湿地生态环境保护具有重要意义。<br />
The carbon cycle is one of the most important biogeochemical cycles on the earth. It is widely in-volved in the exchange of other materials in the surface system and profoundly affects the living environment of mankind. The imbalance between carbon sources and carbon sinks has led to the occurrence of carbon sinks in the atmosphere in recent years. The carbon cycle of wetland ecosystems is an important part of the earth’s carbon cycle system, and it has important ecological value for achieving carbon neutrality. There are many factors for the loss of carbon sinks, including climate change, CO<sub>2</sub> fertilization, increased nitrogen deposition, and changes in land-use patterns. Wetland is one of the ecosystems of the four continents. In-depth understanding of wetland carbon storage status and carbon cycle process is an important basis for the study of global carbon cycle, and it is also one of the important contents of global climate change research. Based on the strategic goal of carbon peaking and carbon neutrality, facing the severe challenge of carbon loss, strengthen wetland scientific research to increase the area of wetland, improve its natural recovery capacity, enhance the existing wetland ecosystem service functions, and discuss wetland ecology. The relationship between system carbon profit and loss is discussed. The low-carbon sink value of natural wetlands is mined to achieve carbon neutrality. Formulating reasonable wetland restoration policies are of great significance to the ecological environment of wetlands.
