米草属植物盐沼湿地甲烷排放研究综述

A Review of Methane Emission from Spartina Plants in Salt Marshes

米草属植物是典型的盐沼湿地优势种,在北美东海岸及墨西哥湾广泛分布,同时作为一种引入种或入侵种分布在西欧沿海湿地及我国广大沿海湿地,并有不断扩大其分布区面积的趋势,构成了全球沿海盐沼湿地的重要组成部分,也是全球重要的甲烷排放天然源。综述了国内外关于米草属植物盐沼湿地甲烷排放研究进展,包括米草属植物盐沼湿地甲烷排放通量、季节变化、甲烷的产生、氧化与传输以及影响甲烷通量的主要因子。

Plants of Spartina are dominant species in salt marshes and widely distributed in the east coast of North America and the Gulf of Mexico. Spartina plants also occur in wetlands in the coast of Western Europe and Eastern China as invasive species or introduced species and tend to expand their distribution. They are an important part of the global salt marshes and a key natural source of methane emission. This paper reviewed the progress made in studies of methane emission from Spartina salt marshes home and abroad,including methane flux, seasonal variation, methane production, methane oxidation, methane transport and the most important factors controlling methane emission
