Soil Carbon Storage In Alpine Kobresia Meadows Wetland In Ruoergai, Qinghai-Tibet Plateau

As a special kind of wetland types,alpine wetland is the richest areas of the species in theworld,and the most abundant peat reserves of natural ecosystems. This article selected studyarea Ruoergai Alpine wetland,which is the typical alpine wetland in the world, and is also thelargest area of highland peat swamp concentrated area in China even in the world, and its hugecarbon stocks play an important role in the mitigation of global warming.This paper combined with field survey and sampling, analysis Ruoergai Alpine Kobresia.Meadows wetland in perennial water-logging, seasonal water-logging and no water-loggingorganic carbon content and carbon storage. The results are shown as following:1.In Ruoergai Alpine Wetland, carbon storage is very huge,and their distribution is so deep.Soil carbon storage of the area is up to0.245Pg (400cm), with a total area accounted for only0.36‰, carbon storage accounted for2.90‰of the country; even in the depth of4m there isstill a considerable carbon reserves, so future research should be more than4m.2.Moisture condition affects soil carbon storage, the study found that under different waterconditions, the same vegetation type in shallow soil showed: perennial water-loggingarea>seasonal water-logging area>no water-logging area.3.In deep soil (under100cm), the carbon reserves of Ruoergai Alpine Kobresia. Meadowswetland is up to0.1366Pg, accounted for55.87%of the entire section, indicating that up to400cm depth soil carbon storage is also abundant, and is an important part of the area of soilcarbon reservoir.4.In different moisture conditions, in the0-400cm soil depth, the soil C/N ratio are lessthan15mostly, which show that: the soil C/N ratio of Ruoergai Alpine Kobresia. Meadowswetland is not conducive to soil microbial decomposing soil organic matter, and is conduciveto the alpine wetland soil carbon accumulation.
