Soil texture fractions and fractal dimension of particle size distribution as predictors of interrill erodibility
Erosion predictor fractal dimension
2011/6/29
Choosing a particular textural fraction as an erodibility predictor is often confusing because various fractions of soil particles have been introduced as erodibility index by many researchers.

Fractal Geometry in Root Systems:Quantitative Evaluation of Distribution Pattern
Fractal Root box Root length Root morphology Root system
2009/7/28
In order to describe root distribution quantitatively, fractal analysis was applied to root systems. Root systems of soybean and garden pea seeldings grown in narrow root boxes (30×41×2 cm) were sampl...
冲击作用下粘性土壤破碎体的分形维数与影响因素(Fragmentation Fractal Dimensions of Cohesive Soil under Impact and Its Influencing Factors)
粘性土壤 冲击破碎 破碎体分形维数
2009/5/22
给出冲击破碎分析的两倍尺度控制约定,研究粘结态土壤破碎体生成的影响因素,建立了土壤破碎体分形维数与落锤质量、冲击行程、土壤含水率、破碎比能之间的关系。结果表明,土壤破碎体的分形维数与落锤质量及冲击行程没有联系,但分形维数与土壤含水率及破碎比能具有明显的相关性。另外,通过比较得知土壤在冲击作用下的破碎体分形维数远远低于植被土样的分形维数。
Fractal scaling of soil particles in agricultural landscapes of Nigerian savannas
soil profile particle size distribution fractal
2008/11/18
Fractal dimensions, D, for soil profiles in the
derived and southern Guinea savanna zones of Nigeria were
calculated using particle size distribution data. The D values
increased with soil depth be...
