A holistic approach, based on the ETR model, has been tested in the area of three catchments with different land cover and landscape management, on the right bank of Lipno water reservoir. The results confirm that holistic concept needs to be considered as a perspective for evaluation of landscape complexes when assisted by the methods of remote sensing, hydrological and hydrochemical monitoring and analysis of economical activities in the landscape. The studied parameters, important for evaluation of landscape function, confirm high degree of their interrelations and correlations. The advantage is a relatively simple and effective evaluation of the state of landscape by two integral variables – surface temperature (satellite photography) and quality of drainage water (continuous measurement of outflow). The use of such an approach requires certain knowledge of the study area.
