The Stagnic Anthrosols developed from quaternary yellow sedimentary parent material occupied an important position in Southwest China.Fractal dimensions of particle size and micro-aggregate size distributions of Stagnic Anthrosols and their relationship to soil micro-structure had been probed.Results showed that the soil particle size distributions were dominated by clay,the fractal dimensions of particle size distributions (Ds) were high and between 2.676-2.925,as the fractal dimensions of micro-aggregate size distributions (Da) were between 2.354-2.853.The fractal dimensions of particlesize distributions were preferably related with the ratio of coarse particles and fine particles (c/f20μm) and the micromorphological feature of skeleton grains.The evolution degree of micro-structure among horizons were reflected by the coefficient of variation of Ds within the profile.The fractal dimensions of micro-aggregate size distributions were related with the quantities,distributions of micro-aggregates and micro-pores.Results revealed that the soil micro-structures could be quantified by fractal dimensions preliminarily.
