[Objective] We aimed to understand the effects of different land use patterns on soil inorganic carbon(SIC) content and storage, in order to provide scientific support for regional carbon transfer principle and grassland management.[Methods] The content and storage of SIC and the main soil physicochemical properties are analyzed, in five different land use patterns including fencing grassland(WF), free grazing land(NG), perennial artificial grassland(RG), reseeding land(BB) and an extreme degradation meadow (HTT).[Results] In alpine meadow ecosystem, SIC content was low, and the SIC storages differed among different land use patterns:RG(3 381.28 kg/hm²) > WF(739.27 kg/hm²) > NG(712.12 kg/hm²) > BB(647.64 kg/hm²) > HTT(361.26 kg/hm²). Soil pH value, bulk density and water content varied greatly among different land use types. SIC content showed a positive relation with soil bulk density while a negative relation with water content. When pH<7, the SIC content was very low and remained constant, in contrast, when pH>7, SIC content increased exponentially.[Conclusions] The planting perennial artificial grassland was more effective than other measures in terms of SIC sequestration and maintaining the function of carbon sink.
