In this study, the organic carbon storage and density distribution characteristics of the soil in the Zhifanggou catchment on the Loess Plateau were studied based on field investigations, laboratory measurement, and geostatistics analysis. The landuse within the catchment was divided into 4 types : farmland, grassland, shrubland, and woodland. It is showed that the soil organic carbon density for different landuse types follows the trend shrubland > woodland > grassland > farmland. In the entire catchment, the proportion of average soil organic carbon density decreases with soil depth. The spatial distribution of the soil organic carbon density is closely related to the landuse types and topography. The relationship between soil depth and total organic carbon storage is linear.
