THE EVALUATION OF VISUAL INFLUENCES ON THE ENVIRONMENT OF IVANO-FRANKIVSK CITY

Abstract

The article deals with the problems of urban systems visual contamination which is connected with the issues of noise and electromagnetic loading, waste utilization and storage, water resources pollution, and which depends entirely on the environmental situation within the cities. The paper analyzes Ukrainian and foreign publications on the factors of visual evaluation, particularly the calculation of the coefficient of videoecological susceptibility of the territory, the statistical analysis of visual pollution estimation based on the poll of the respondents who are exposed to negative visual impact. The authors reveal that in Ukraine there are no normative documents which regulate the procedure for the estimation of visual contamination. The article presents the main drawbacks and unresolved parts of the general problem of visual impact evaluation. The authors of the publication suggest a generalized method for conducting a visual evaluation of urban areas. The results of the estimation are presented using the urban system Ivano-Frankivsk as the example. The main stages of the evaluation of visual influences are highlighted. These stages are the city zoning according to the presence and types of dominant visual objects, the clarification of the list of those criteria which are necessary to evaluate the quality of the visual environment, the choice of the optimal solution concerning the evaluation procedure and regarding the selection of the appropriate number of points on the urban system territory, and, finally, carrying out the evaluation itself in accordance with thirty criteria. The authors of the publication substantiate visual evaluation procedure based on the suggested method together with some elements of the method of multi-criteria analysis. Using the results of the evaluation, the authors construct the map of visual influences and carry out a complex spatial analysis of the visual fields of Ivano-Frankivsk. The article solves the problem of comprehensive evaluation of the ecological situation of urbanized systems and living conditions of the population, taking into account the evaluation of the visual environment quality.
