Abstract

This article focuses on the seasonal and spatial changes of CH₄ emission from the natural reed marsh of Liaohe Delta, China. Field experiments showed that this natural wetland acts as a CH₄ sink in spring (-30∼-1000 μg/m².h), a strong source in summer (400-3000 μg/m².h) and a weak source in autumn (<400 μg/m ².h). Reed plants play an important role in transportation and emission of methane produced in soil. According to our field measurement data, CH₄ emission is positively related to temperature, and negatively related to Eh value and water depth. The activity of methanogenic bacteria is higher in the rhizosphere and surface layer, and thus contributes more in CH₄ emission than other layers.
