| 摘 要： | 在安徽土壤普查数据的基础上,对皖南地区水稻土的分形特征进行了研究,结果表明:(1)该地区水稻土的分形维数D介于2.6717-2.9117之间,D分别与国际制粗砂粒和细砂粒含量呈明显的负相关,与粉砂粒和粘粒含量呈显著的正相关,其中与粘粒的相关关系达到极显著水平.(2)用分形维数代替土壤颗粒组成来研究土壤肥力特性,结果表明它可以较好地作为水稻土肥力特性的定量化指标.

| Abstract: | On the base of general investigation of the soil in Anhui Province, the fractal features of paddy soil in the southern area are studied. The result of this study demcnstrates that firstly, fractal dimension of particle surfaces are 2. 6717-2.9117 in paddy soil of this area. The fractal dimensions are 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, the fractal dimensions of particle are positively relative with the content of clay. Secondly, the features of soil fertility are studied by using the fractal dimension, which can be used as a quantitative index of soil fertility, instead of soil particle composition. |
