Abstract :Some results of a case study which is focused on regional environment evaluation with geochemical
survey data and remote sensing images are described in detail in this paper. A land cover map compiled on the
basis of Landsat TM images and geochemical data was used to establish a model that provides quantitative data for
ecological and environmental evaluation.
