【摘要】 运用土壤颗粒表面分形维数计算方法,研究了吉林玉米带耕层黑土颗粒表面的分形维数特点。结果表明:耕层黑土表面的分形维数为2.794～2.938,并且有从北向南增加的趋势。土壤颗粒表面分形维数与容重、有机质含量的复相关系数达显著水平,且与有机质含量、土壤孔隙度具有显著相关性。更多还原

【Abstract】 Fractal dimensions of particle surface in corn belt phaeozem of Jilin were studied. The results indicated that fractal dimensions of particle surface were 2.794～2.938 in the belt and it had a tendency of increase from the north to the south. Statistic analysis indicated that fractal dimensions were in the partial correlation with bulk density and content of organic matter of soil. In addition, it is in significant correlation with content of organic matter and pore space of soil.更多还原
