The environment in the towns is the synergetic unit, characterized by its variability complexity, spatial character and high dynamics of its development. The diagnostic of its condition must exceed a level of the qualitative and quantitative analysis of its elements. For the coordination of the processes in the environment we must know the function of the subsystems and entities and their synergetic efect. Keywords in this issue are: dynamics of the system and its stability, self-regulation, self-organisation, proportionality, time- and spatial-succession, homeocyclic, backcoupling and intercommunication of the subsystems, active and restrictive operative interference, dynamical prognosis. This aspect must be a basis for the diagnosis of the condition of human living environment, for the analysis of the processes, a synthesis and proposal of the operative strategy by its protection and creation, and for choice of the applied methods.
