In this paper, soil physical and chemical characters of 195 kinds of sandy soils under different utilization sampled from Zhangwu County were studied. The results showed that Zhangwu County area generally desertified generally and heavily, displaying the nutrient to be barren and soil particle to be large. The heavier the degree of desertification led to the lower soil fertility. Different land use pattern and different physical and chemical characters caused different the degree of desertification. The degree of desertification was farmland >woodland >grassland. Human factors seriously influenced farmland and the content of fine grains in farmland increased. The soil fertility of farmland greatly improved by fertilization and the content of phosphorus increased remarkably.
