摘要:Meadows are among the planet’s effective natural ecosystems for sequestering (capturing and storing) carbon (C).Quantifying the C sequestration capacity is therefore critical for successfully managing ecosystems to maintain their substantial abatement potential.Taking meadows in Qilian County and Menyuan County of Haibei in Qinghai as the research objects,through field investigation and sampling of grassland,the soil organic matter of grassland was analyzed and calculated; the influence of different factors on carbon fixation potential value was investigated.The following main conclusions were obtained: in the process of returning farmland to grassland,both artificial grassland and farmland have a large carbon sequestration potential.The main influencing factors of effective radiation,temperature,soil thickness and precipitation all affect the carbon sequestration potential value.
