中文摘要：

湿地是一种具有独特水文、土壤、植被与生物特征的生态系统，分布于陆生生态系统和水生生态系统之间。湿地在调节气候、蓄洪防旱、净化环境、涵养水源、促淤造陆、控制土壤侵蚀、维持生物多样性和生态平衡等方面具有十分重要的作用。湿地对温室气体的影响日益引起关注，湿地既能通过植物光合怍用吸收CO2，也能在碳氮物质循环过程中释放CO2、CH4和N2O。媪室气体的过量排放会导致温室效应，通过改变大气层辐射来影响地球气候系统，从而使全球气候变暖，进而产生一系列连锁反应，如海平面上升、冰川融化等。

英文摘要：

A review was made on the factors influencing the emission of greenhouse gases, carbon dioxide, methane and nitrous oxide from wetlands. It was found that greenhouse emission from wetland was mainly affected by vegetation, hydrology, soil condition, climate and human disturbance. Based on the analysis of the development and problems of the previous studies, we suggested that future study on greenhouse gases emission from wetland should be focused on the production mechanism, the relationship of the related factors and the reduction technology. Measures were proposed to improve the management of greenhouse gases of wetlands.
