【 摘 要 】

Land-use changes from the conversion of grassland and cropland are typical agricultural production mode that constitute one of the important sources of atmospheric methane(CH4). Traditional grasslands have been experiencing conversion to croplands for pursuing higher economic benefits over the past decades in the arid and semi-arid lands of Asia. How the land-use changes in grasslands conversion to croplands altered the soil properties and the CH4 uptakes remains unknown. Articles retrieved from SCI periodicals are summed up and refined to find the effects on the CH4 uptake in the land-use change. In order to set up the basis on measures to mitigate greenhouse gas emissions. The results of this study suggest that The production mode of land-use change that traditional grasslands was converted into croplands for pursuing higher economic benefits over the past decades would also probably lead to a higher ecosystem CH4 uptake rate and needs to be stopped in the arid and semi-arid lands of Asia.
