影响湿地甲烷产生、传输与氧化因素的研究进展

湿地甲烷排放对温室效应的贡献十分明显。湿地甲烷排放是有机物（底物）输入、分解、厌氧产甲烷以及甲烷传输、氧化等环节综合作用的结果。文章对影响湿地甲烷生成、传输与氧化的温度、水位、土壤有机物、土壤pH和氧化还原电位、植物类型以及土壤离子、土质等主要因素进行了阐述，对未来湿地甲烷排放变化趋势进行了探讨，并对此方面的研究方向进行了分析，旨在为全球气候变化以及人类活动影响导致大气甲烷浓度变化预测提供依据。

The factors influencing generation,transmission and oxidation of methane in wetlands:A review

Methane emitted from wetlands contributes significantly to greenhouse effect.Methane emission is resulted from the combined actions of input and decomposition of organic matter and production,transmission and oxidation of CH₄.The most important variables controlling CH₄ flux including temperature,water level,vegetation,and organic matter content,pH,redox potential and properties of soil are discussed The change in future trend of wetland methane emissions is discussed as well.Future research directions are then analyzed.This review provides the basis for prediction of atmospheric methane concentration with the consideration of global climate change and human activities.
