Espaços livres públicos potenciais para o lazer e a recreação da cidade de Santa Maria, RS

Abstract

This dissertation presents the identification, analysis and evaluation of open spaces in the middle city of Santa Maria, Rio Grande do Sul, Brazil. Through the methodological contribution of multicriteria analysis, the research aims to identify the potential public open spaces for leisure and recreation on the macro scale of the urban perimeter of Santa Maria. The justification and relevance of this study is given: the absence of the use of geotechnologies combined with landscape analysis methods in Santa Maria; the public spaces for leisure and recreation are insufficient in terms of quantity, service radius, size, connectivity, accessibility and landscape quality; and by the fragmentation of these open spaces with areas of great environmental value such as the Permanent Preservation Areas. The adopted methodology is the Multicriteria Decision Analysis and the Analytical Hierarchy Process in geoprocessing. Multicriteria analysis allows the definition of search criteria for existing open spaces and their evaluation through the hierarchical attribution of values, called notes and weights. The seven criteria chosen are: Areas for the Permanent Preservation of Water Resources, Special Natural Areas, Urban Voids, Population, Income, Open Spaces of Historical, Heritage and Cultural Interest and, Open Spaces for Circulation. From the results, it was observed in the synthesis map of extreme, high, moderate and low priority of potential of open spaces, that the areas of high natural potential and high socioeconomic vulnerability should have priority in the planning of the Santa Maria Open Spaces System . Finally, it is concluded that the multicriteria assessment allows the proposal of guidelines for the implementation of future squares, parks, green corridors and other areas of public leisure and recreation. Thus, the present study reinforces the importance of combining the analysis of the physical support of the landscape with the socioeconomic data, making them compatible in actions that make the sustainable planning of the Open Spaces System more flexible, especially the public open spaces for leisure and recreation a short, medium and long term.
