Análise Da Complexidade Do Saldo De Radiação Em Uma Floresta Sazonalmente Inundada No Norte Do Pantanal

Abstract

Análise da complexidade do saldo de radiação em uma floresta sazonalmente inundada no norte do pantanalAnalysis of the complexity of net radiation in a seasonal flooded forest in the northern Pantanal AbstractThe ecosystem net radiation has a complex variation, and represents the energy available for physical and biological processes that occur between the vegetated surface and atmosphere. Therefore, the objective of this study was to analyze the complexity of net radiation measured above the canopy of a seasonal flooded forest in the northern Pantanal from the perspective of complexity theory. The attractors were seasonal reconstructed by the estimation of the exponents correlation dimension (D 2(wet) = 1,73±0,05 and D 2(dry) = 1,36±0,18), embedded dimension (m = 7), rate of recurrence (RR (wet) = 0,144±0,004 and RR (dry) = 0,169±0,002) and determinism (DET (wet) = 0,896±0,013 and DET (dry) = 0,973±0,015) data sets analyzed. The results showed the existence of strange attractors of low fractal dimension, and sensitive to the seasonality of radiation balance.
