Abstract


The study of the micrometeorological variables dynamics is important for understanding the ecosystems function. The evolution of these systems is difficult to comprehend when they have been analyzed by traditional linear methods. This implies the need for the use of methods of observation and theoretical description of the phenomena that takes into account the non-linearity of the equations of motion of the dynamics of such complex systems. The objective of this study was to determine the fractal dimension of micrometeorological variables series in a floodedplain forest in the Pantanal of Mato Grosso. Estimates of the fractal dimension Dc and dimension of immersion m of micrometeorological variables of global radiation, photosynthetically active radiation, temperature and relative humidity, evapotranspiration, CO2 flow and CO2 concentration showed the existence of coupling nonlinear subsystems low dimension ruled by strange attractors, because the number and the variety of interactions.
