湿地仅占全球陆地表面很小的一部分，却是全球陆地生态系统的碳汇，在全球碳循环中发挥着重要的作用。湿地排水后，地表水位下降，湿地土壤有氧层增加，CO2排放速率增加，CH4排放速率减少，进而影响湿地生态系统的碳汇功能。综述了当前国内外有关湿地排水对土壤CO2和CH4温室气体和土壤有机碳储量影响的研究进展，研究表明：森林湿地选择适当择伐可能有利于减缓大气温室气体（CO2和CH4）的排放。这将为我国基层林业局湿地恢复和碳管理，以及湿地经营提供参考价值。

Wetlands account for a small proportion of the earth’s land surface, but they are important global terrestrial carbon sinks, and play an important role in global carbon cycle. Draining of wetland lowers the level of ground water, increases the thickness of aerobic soil, increases the emission rate of carbon dioxide (CO2) while reducing that of methane (CH4), furthermore, affects the function of carbon sinking of the wetland ecosystem. This paper reviews the progress at home and abroad in studies of the effects of draining on emission of CO2 and CH4 and soil carbon storage. Results indicated that appropriate selective cutting of trees in forest wetland helps to reduce the emission of CO2 and CH4, providing a theoretical basis for wetland restoration and carbon management for local forestry bureaus.
