Abstract: Dung deposition is one of the main ways that grazing affects grassland ecosystem. In this paper, the research progress on the process of dung decomposition and the effects of dung deposition on the soil physical and chemical properties, soil microbial activity, plant community structure and biomass, and livestock grazing pattern of grassland ecosystem were reviewed, and the future research on the dung deposition on grassland ecosystem was proposed.
