摘要: With the increase of population and the demand for food and fiber, some natural grassland was reclaimed to farmland in China. CO2 emission and CH4 uptake fluxes were measured during the growing season of natural grass, Erect millvtch grassland, maize and potato during 1997-1998. The results indicate that the conversion of native grassland to agricultural uses has increased the CO2 emission from soils and decreased CH4 uptake from the atmosphere.
