摘    要:四川 1 6个耕地表层的土壤颗粒表面分形维数D为 2 80 5~ 2 942 ,其中砂土2 82 1、壤土 2 870、粘壤土 2 91 6和粘土 2 939。统计分析表明D分别与国际制粗砂粒和细砂粒含量呈极显著负相关 ,与粉粒和粘粒含量呈极显著正相关 ;它与粉粒、粘粒和有机质含量的偏相关关系达极显著水平 ,与容重的偏相关关系达显著水平

关 键 词:土壤  颗粒表面  分形维数  容重

Abstract:Fractal dimensions of particle surface were 2.805~2.942 in the plowed layers of 16 crop fields in Sichuan. Among them, sand soil was 2.821, loam soil 2.807, clay loam soil 2.916, and clay soil 2.939. Statistic analysis indicated that fractal dimensions were in highly significant negative correlation with the contents of coarse sand and fine sand, and in very significant positive correlation with the contents of silt and clay. In addition, in the partial correlation with the contents of silt, clay, organic matter and bulk density of soil was highly significant or significant.
Keywords:Soil  Particle surface  Fractal dimension  Bulk density
