    摘要:

    土壤团聚体和水稳性团聚体的状况是影响土壤肥力的一个重要因素.本文运用分形模型对不同林分经营模式土壤团粒结构进行研究,探讨了分形维数与土壤肥力的关系.结果表明:土壤水稳性团聚体及水稳性大团聚体含量越大,团粒结构的分形维数越小,土壤肥力越高;土壤团粒结构的分形维数与水稳性团聚体含量及水稳性大团聚体含量之间存在显着回归关系;分形模型为土壤肥力研究提供新方法.

    Abstract:

    The status of soil aggregates is an important factor affecting soil fertility.In this work,the fractal model was used to study the soil aggregate structure under different stand management patterns and to inquiry the relation between fractal dimension and soil fertility.The results indicated that the higher the content of water stable aggregates and water stable big aggregates in soil,the smaller the fractal dimension of soil aggregates,and the higher the soil fertility.There were remarkable regression relationships between the fractal dimension of soil aggregates and the contents of water stable aggregates and water stable big aggregates.The fractal model could be a new tool for the research on soil fertility.
