PAZ PELLAT, Fernando et al. Multifractal Analysis of Soil Organic Carbon: 1. Universal Scaling Function. Terra Latinoam [online]. 2008, vol.26, n.2, pp.183-191. ISSN 2395-8030.

In this paper, the requirements of soil organic carbon (SOC) inventories are discussed under the perspective of the national communications commitment to the United Nations Framework Convention on Climate Change. Using considerations of scale effect and spatial variability of SOC, the theory of multifractal processes, conservative or not, is introduced as a strategy for characterizing universal multiscaling functions in order to estimate SOC at different scales of observation. The estimation of the multifractal function of SOC was performed using a data base of 4583 samples gathered over the period 2001-2002. The SOC universal scaling function parameters were estimated and the estimation problem was reviewed from the perspective of the divergence of statistical moments of multifractal processes.

Palavras-chave : soil carbon inventories; scaling functions; conservative and non conservative processes.
