Improving the methodology for assessing the level of environmental safety of urban areas as the basis of their life cycle

Abstract

The article presents a graphical description of the relative environmental, economic and social indicators in the form of planar diagrams reflecting the state of the industrial and economic functional zones under study. Previously, we have described modern changes in the infrastructure of the urbanized areas, and also justified the necessity of supplementing economic and social indicators with environmental ones. On the basis of the conducted analysis, we have compared each of the indicators of the state of the environment of the urbanized areas with allowable values. In turn, the obtained values of relative indicators are graphically presented in the form of planar diagrams that reflect the most significant characteristics (environmental, economic and social) of the objects under study, on the scales of which the values are equal to 1 characterize the negative value of the corresponding characteristic, and the values are close to the reference point - the most favourable. In further research we plan to continue improving the methodology for assessing the level of environmental safety of the urbanized areas with the aim of its practical testing and implementation. The scientific novelty of the study consists in combining the obtained values of environmental, economic and social characteristics into a comprehensive (integral) assessment of the urbanized territories environmental safety level that would serve as the basis for subsequent selection of environmentally effective and cost-efficient organizational, technical and special environmental engineering measures.
