【摘要】 湿地生态系统是影响气候变化的活性气体的重要"源"或"汇",随着人类活动的增加和气候变化的加剧,湿地生态系统活性气体对全球气候变化的影响越来越受到关注。已开展的研究主要集中于二氧化碳（CO₂）、甲烷（CH₄）、氧化亚氮（N₂O）和二甲基硫（DMS）等活性气体。本文综述了湿地生态系统CO₂、CH₄、N₂O和DMS的交换通量、时空变化特征以及影响因素。然而,目前对湿地生态系统活性气体的研究还不够系统和深入,对不同类型湿地的活性气体的源汇格局,碳氮硫的耦合作用机制、人类活动和环境压迫的影响等开展系统地研究,才能定量评价其对全球气候变化的贡献,并阐明变化趋势。更多还原

【Abstract】 Wetland ecosystems are important "source" or "sink" of active gases that affect climate change. With the increase of human activities and the intensification of climate change, the impact of wetland active gases on global climate change has attracted more and more attention. Many researches on carbon dioxide（CO₂）, methane（CH₄）, nitrous oxide（N₂O） and dimethyl sulfur（DMS） have been carried out. The study progress of wetland active gases, including exchange fluxes, variation characteristics and influencing factors of CO₂, CH₄, N₂O and DMS are summarized in this paper. However, the researches on wetland active gas are not systematic and in-depth. The source and sink patterns of active gases from different types of wetlands, the coupling mechanism of carbon, nitrogen and sulfur, the impact of human activities and environmental stress etc. should be systematically studied in order to quantitatively evaluate their contribution to global climate change and put forward the change trend.更多还原
