The complex Landau-Ginzburg equation (CLGE) has been used as the basis of the study of spatially distributed systems. We considered a variety of behaviors on a fluid, such as lami-narity, the apparition of sources and sinks, the intermittent regime, and the defect-mediated turbulence; being the last one that focused our attention. Numerical analysis of the CLGE allowed us the spatio-temporal characterization of each of these behaviors. By means of the parameters space, based on the mean amplitude, the phase diagram distinguishes clearly the occurrence of the above mentioned regimes
