Abstract:: For evaluating the effect of different forest stands on soil structure and function, characteristics of soil particles fractal under four typical vegetations types in Yiyuan limestone mountain were studied according the quality principle of soil particle size distribution and theories of soil fractal. Results indicate that: (1) The soil particle size distribution of different vegetation types varied greatly. The clay and silt content of woodland is significantly higher than that of shrub-grassland. (2) Soil particles fractal dimension of woodland is significantly higher than that of shrub-grassland, and to the greatest is Platycladus orientalis+Euonymus fortunei mixed, the lowest is shrub-grassland. (3) The soil particles fractal dimension of the different vegetation types has a significant positive linear correlation between the clay and silt and fine gravel content of soil, a negative linear correlativity obviously to the coarse gravel content of soil. (4) The soil particles fractal dimension of the different vegetation types has a significant negative linear correlation with the uneven coefficient. In addition to shrub-grassland, the other three typical forest stands are good structural soil in gradation and uneven coefficient. Soil particles fractal dimension is an important quantitative index in appraising soil structure and texture among different vegetation types.
