| 摘 要： | 以土壤颗粒组成数据为基础，分析了我国土壤颗粒组成的分形维数。结果表明，不同质地的分形维数存在一定的差异，分形维数随土壤质地的变细而增大；由北至南、由西向东和由西南至东北，我国主要地带性土壤的分形维数逐渐递增；成土母质对土壤质地分形维数有很大影响，易风化母质上发育的土壤质地分形维数高于难风化母质上发育的土壤。

| Abstract: | This paper analyzed the fractal features of particle size distribution (PSD) of soils in China. The results showed that:various soil textures had different fractal dimensions, the fractal dimensions of PSD of soils increased with soil texture fining; from west to east, from north to south and from southwest to northeast, there were decreasing tendencies in the fractal dimensions of PSD of soils; and the parental materials had evident influences on the fractal dimensions of PSD of soils. |
