| Zusammenfassung |
| Pedodiversity, the study and measurement of soil diversity, may be
considered as a framework to analyze spatial patterns. Recently, selfsimilar
multifractal patterns have been recently reported in the pedotaxa-abundance
distributions at the planetary scale. This is the result to be expected from
the complexity of earth soil systems. When the state of soil is understood
as the outcome of nonlinear chaotic dynamic, highly irregular patterns with
so-called multifractal behavior should be common. This opens the opportunity
to use parameters of fractal theory to characterize pedodiversity. We
compute Rényi generalized dimensions for the abundance distribution of
pedotaxa for the five landmasses and the whole World drawn from the most
detailed available global dataset based on the second level of the FAO 1974
classification units. We explore the effective relationship between
diversity indices and Rényi dimensions. We show how multifractal
analysis unifies diversity indices and how they should be interpreted
offering a coherent perspective with a single mathematical procedure to
analyze spatial patterns of the pedosphere. |
