Soil is the main source or sink of greenhouse gases (such as CO_2,CH_4,N_2O). Land use change would influence soil micro-environment and microbial physiological and biochemical processes,and thus significantly affect greenhouse gas fluxes from soils. Under the global change and significant changes in land use,the international community has gradually carried out researches on the effect of land use change on greenhouse gas fluxes from soils. This paper briefly describes the research status of land use change and greenhouse gas fluxes from soils,focuses on the effect of cropland,inter-conversion of grassland and forest,conversion of wetland to cropland, inner changes in different land use types (forest,grassland,wetland and cropland) on the greenhouse gas emissions,and explains its main impact mechanism from the key processes of greenhouse gases produced from soil. We concluded our review with an analysis of deficiencies in current research,and pointed out some urgent and key directions in future,aiming at providing some value references to carrying out the research in the future.
