An arid region located in Linz County, Gansu Province, consisted of desert, cropland and wetland was investigated. The vertical patterns of SOC density in the 3 different landscapes and the horizontal distribution of SOC density in the study area were evaluated. The differences in SOC density among different landscapes and soil layers were analyzed, and the primary factors influencing SOC density were determined. it is highlighted that : 1) Wetland and desert had the highest and the lowest SOC, respectively; 2) Fine particles were the major determinant of SOC for desert and cropland; 3) Wetland and desert both have the potential to be C sinks.
