湿地碳排放及其影响因素
Wetland methane and carbon dioxide emission and affecting factors.
摘要
Abstract
Wetland ecosystem plays an important role in global carbon cycle. Its unique soil, hydrology , and vegetation make the wetland able to constantly accumulate carbon in the hypoxic environment, and also, release large amount of greenhouse gases CH4 and CO2. Wetland carbon emission has become a hotspot in the study of global climate change. The differences in the soil status, hydrological condition, and vegetation type in wetland result in a strong spatiotemporal variability of CH4 and CO2 emission from wetland. It' s observed that the CH4 and C02 emission is positively correlated with soil temperature, and affected by water level to a certain extent. Within a certain range, soil anaerobic condition leads to the increase of CH4 emission and the decrease of CO2 emission. Vegetation affects all aspects of the greenhouse gases production, oxidation, and emission, and the affecting degree varies with plant species.关键词
