湿地碳排放及其影响因素OA北大核心CSCDCSTPCD
Wetland methane and carbon dioxide emission and affecting factors.
湿地生态系统在全球碳循环中起着重要作用.湿地独特的土壤、水文和植被条件,使得其在低氧环境下能不断累积碳,并同时释放大量温室气体——CH4和CO2,因此湿地的碳排放近年来成为全球气候变化研究关注的重点问题.湿地的土壤状况、水文条件及植被类型的不同导致湿地CH4和CO2的排放具有极强的时空变异性.土壤温度与CH4和CO2排放呈正相关关系；水位条件对湿地温室气体的排放有一定影响,在一定范围内,土壤的厌氧环境导致CH4排放量增大,CO2排放量减小；植被影…查看全部>>
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 spatiotempor…查看全部>>
