Abstract:: Taking field sampling, and using laboratory analysis method and the fractal theory of particle volume, we studied soil particle-size distribution and fractal dimension of different land use types. The results showed that:(1) soil ammonium nitrogen, nitrate nitrogen, available phosphorus, total phosphorus, total nitrogen and organic matter content of different land use types were significantly higher in forestland and grassland than those in the cultivated land and farmland (p < 0.05), were not significantly different between forestland and grassland had (p > 0.05); (2) coarse silt was dominant in soil, in addition to the coarse sand grains, the land uses had significant effects on the contents of the rest fractions, the hierarchy was not obvious, and fractal dimension of soil particles was 45.98%～67.12%; (3) fractal dimension of soil particles increased with the soil depth, and there was a lower rangeability in the surface soil layer and a higher rangeability in 40—50 cm soil layer; (4) regression analysis showed that there was a strong negative liner relationship between soil particle-size and fractal dimension; (5) correlation analysis showed that fractal dimension significantly positively related to soil moisture content, and significantly negatively related to soil organic matter content, positively related to soil nutrients. In total, the land uses of loess hilly-gully region have the greater influence on soil particle composition, the particle sizes of grassland and forest land shift from the small particles to the large particles compared with farmland.
