Abstract:: We toke soil organic carbon data of 1980 and 2010 in Fujin to analyze the effect of land use change on the surface (0—30 cm) and spatial distribution of soil organic carbon storages by using the method of combination of Geostatistics and GIS. The results showed that soil organic carbon pool (0—30 cm) in Fujin showed the decreasing trend from 1980 to 2010. The soil organic carbon pool was 107.12 Tg C in 1980, it was 94.39 Tg C in 2010. And it reduced by 13.49%. The distribution of land use change in the study area mainly was that wetlands, dry land and meadow reduced in central and southwestern regions. The paddy fields, woodland and water bodies in the north had increased. Soil organic carbon densities of different land cover types in two periods decreased in the order: wetlands > forest > grassland > paddy field > dry land. Marsh reclamation and paddy field change are the major factors on the spatial and temporal changes in soil organic carbon storage of Fujin.
