英文摘要	The Horqin Sandy Grassland is one of the most seriously desertified areas in China's agro-pastoral ecotone due to its fragile ecology, combined with improper and unsustainable land management. We investigated organic carbon changes in bulk soil (0 to 5 cm), light fraction of soil organic matter, and soil particle-size fractions induced by land-use and cover type changes. The results indicated that total soil organic carbon (SOC) storage decreased by 121 g/m(2) with the conversion of grassland into farmland for 30 years, and increased by 261 g/m(2) with the conversion of grassland into plantation for 30 years. Total SOC storage decreased by 157 g/m(2) as a result of severe grassland desertification due to long-term continuous livestock grazing, whereas total SOC increased by 111 g/m(2) following the practice of grazing exclusion (16 years) in desertified areas. Changes in land-use and cover type also show great effects on carbon storage in soil physical fractions.
