Abstract Oasification and desertification are the basic geographical processes in arid area. The Cele oasis in Xinjiang, in which oasis expanded obviously in recent years and serious wind erosion affected perennially, was selected as study area to study the regional variations of soil particle distribution (PSD) in farmland with four typical utilization intensities. Meantime, the seven soil nutrient properties such as organic matter were analyzed. The analysis of volume fractal dimension of soil PSD indicated that soil PSD was significant different between farmlands with different utilization intensities. The soil PSD of farmland located on oasis interior was significantly in the highest level, and because the soil PSD of farmland located on desert-oasis ecotone was obviously affected by human factors such as the manure input etc, the soil PSD of farmland without manure input was in the lowest level and even lower than plots covered with nature plant. The soil nutrient properties were also significant different between farmlands, and their changes trend were similar with the PSD. The five soil properties were significantly positively correlated with PSD, and the synthesis index calculated from soil nutrient properties were also significantly positively correlated with PSD. This showed that studying soil PSD during oasification had a specific meaning.
