| 摘 要： | 通过分析水耕人为土颗粒分形维数与土壤质地、耕性、土壤有机质、全N、P、K、pH、CEC等的关系,探讨利用土壤颗粒分形维数作为水耕人为土分类指标的可能性.结果表明:西南地区26个水耕人为土的土壤颗粒分形维数介于2.6175～2.9109之间,平均值为2.8199,土壤颗粒分形维数可作为土壤质地与土壤表面积的综合性定量化指标.适宜耕作的10个土种(2号除外)分形维数介于2.7018 ～2.8116,不适宜耕作的16个土种(23号除外)分形维数介于2.8353 ～2.9109之间.土壤分形维数可表征水耕人为土的质地、成土母质、肥力特征、耕性等,土壤颗粒分形维数可作为水耕人为土分类,尤其是基层分类的一个重要指标.

| Abstract: | The possibility of fractal dimension as a diagnostic index in taxonomy of Stagnic Anthrosols was discussed by means of probing the relationships between fractal dimensions and soil properties,such as soil texture,farm performance,organic matter,pH,CEC,total N,P,K,and so on.The results indicated that fractal dimensions could be regarded as quantitative index of soil texture and CEC.The fractal dimensions were between 2.6175 and 2.9109,and its average value was 2.8199.The fractal dimensions of suitable farmin... |
