The territorial system is considered as an operational unit, and it defined as the territory associated to a community at different levels (macro-, mezzo- and micro-scale), functioning together, based on a project and having a common objective. The evaluation of primary eco-energies started from the idea there is a direct relationship between the way of using lands and the quantity of primary eco-energies. The highest values are considered those from the compact forested massifs, and the most reduced are those from the strongly urbanised areas and from natural areas excessively degraded. Consequently, this study aimed to demonstrate the hypothesis according to which the consumption of primary eco-energies is different, depending on the intensity of the anthropic process. The correlation analysis is carried on two samples, revealing the particularities existent at macro-scale (Romania) and micro-scale (the territorial system Sărăţel, Buzău County). By overlapping the detailed map regarding the quantity of primary eco-energies and the map of the degree of anthropic process, elaborated by common kriging, there were obtained areas which spatially prove the existence of a reverse relation. The anthropic pressure in case of a territorial micro-system (Sărăţel) suffered modifications, but the processes of consumption and degradation of primary eco-energies were continuous and even accelerated, due to the fragility of natural components. The empirical research which was unfold may constitute an alternative to the sometimes very sophisticated studies which measure complex processes, as those of consumption and degradation of primary eco-energies. This may offer arguments for the defining of some territorial policies which could limit the negative effects of extensive urbanisation and ensure caution in direct interventions upon natural and social-economical structures of some fragile territorial systems.
