摘要

甲烷是一种重要的温室气体,对地球气候的形成有重要影响.湿地甲烷在大气甲烷的各种排放源中占有很大比例.本文对湿地甲烷的产生、排放及其影响因素,对其在时间和空间上的差异性规律等方面进行了综合评述.

Abstract

Methane is an important greenhouse gas. Its relative potential for thermal absorption is 30 times greater than that of CO2. About 80% of methane in atmosphere is from organic source. Wetland is an important source of CH4 emissions on a global scale because of the anaerobie conditions created by flooding soils. Methane emits from wetland to atmosphere only when production rate of methane is higher than oxidation rate of methane. The article discusses the present conditions of research on production and e-mission of methane and gives a suggestion of further research on emission of methane in wetland.
