摘　　要：通过对土壤圆锥指数的时空变异序列重新构造ｍ维相空间Ｒ￣ｍ，根据关联函数的定义，计算出土壤圆锥指数的关联维数，其结果将为进一步认识土壤特性的混沌现象提供新的概念和途径。Embedding phase space(R￣m)is reconstructed from the spatial and temperal series g(x)of soil cone indices that were recorded by penetrometer.Based on the definition of relativefunction C(r),the relative fractal dimensions of soil cone indices are calculated with respectto various parameters,The object of this paper is to put forward a new concept or way torecognize further the chaotic phenomenon of soil properties in paddy fields.
