| 摘 要： | 在四川丘陵区的遂渝铁路遂宁站附近，以自然边坡的自然边坡土、铁路切挖边坡的岩石源植生土、铁路切挖边坡的农田源植生土3种不同类型边坡土壤为对象，对不同类型边坡土壤的团聚体差异性进行了研究．结果表明：岩石源植生土的水稳性团聚体含量显著小于农田源植生土，土壤结构破坏率表现为岩石源植生土〉自然边坡土〉农田源植生土．岩石源植生土、农田源植生土和自然边坡土的分形维数分别为2．605，2．700和2．706，岩石源植生土的分形维数显著小于农田源植生土和自然边坡土，而农田源植生土与自然边坡土的分形维数之间无显著差异．土壤颗粒平均重量直径和几何平均直径在不同类型边坡土壤之间存在显著差异，均表现为岩石源植生土〉自然边坡土〉农田源植生土．

| Abstract: | This paper has studied differences of the soil aggregate among three types of slope soil:the soil from naturally developed slope(NS) the soil from the cut-slope surface covered with rock fragment(FS) and the field soil(RF) near Suining Station of Suining-Chongqing railway in the hilly area of Sichuan Province of China.The analysis of soils reveals that the content of water stable aggregate of FS is markedly lower than that of RF.The soil structure destruction rate shows the following order:FS>NS>RF.The frac... |
