The article investigates the ecology factors of environment and medicaldemographycal situations of sickness rate and populations’ mortality demonstrated with an example of urbanized landscapes of Bucowina. A greater corrective connection is revealed among cancer apathy (r=0.5-0.6), general dent rate (r=0.5), and an integral index of ecological safety of city’s landscape environment. The authors revealed backward (negative) dependency among the increased harshness of drinking water and cancer pathology of digestion organs and abdominal cavity. This article deals with synthesis of medical-demographic study results of anthropic landscapes under the aspect of their utilization in order to increase human ecological conditions. One of the problems that authors tried to solve in the process of research lies indeveloping of theoretical and methodological thesis (based on combined analysis ofecological factors and demographical status) in order to determine ecological situation inthe region and to evaluate life and activity conditions of population.
