Summary:利用颗粒分形理论对东北黑土土壤无机颗粒和有机无机复合体的分形维数进行计算,并分析其分布特征以及与土壤肥力的关系。结果表明：东北黑土无机颗粒分形维数主要分布在2.80～2.90,与各粒级均呈极显著相关。有机无机复合体的分形维数主要分布在2.66～2.93,与黏、粉粒级有机无机复合体分别呈极显著正相关和负相关。无机颗粒和有机无机复合体的分形维数间的回归方程y=88.18x-60.73x2＋10.57x3,表明无机颗粒复合有机质可降低土壤的分形维数,但受低温的影响,也可能使土壤复合度降低,进而增加土壤的分形维数。土壤颗粒的分形维数与肥力的相关分析证实无机颗粒复合有机质后,可增强土壤养分的保蓄能力,并在养分释放过程中起到缓释作用。 Soil structure is the material base of soil fertility and has an important significance in soil fertility.In order to study the relationships between soil particles and the f
