Procedimentos metodológicos para estimativa do índice de áreas verdes públicas. Estudo de caso: Erechim, RS.

Abstract

The urban ambiental quality, in terms of proportionable beneficence for value of Indice to the Green Public Areas (IAVP),influenced the used concept and methtodologyc properties (influence area) to the multiple categories of public green areas space distributed in city, the present study had as objective to analise the interference area of influence in different categories of public green areas and consequently in ambient quality of Erechim (RS). Two distinct methodologyc procedures had been considered, based respectively in the total use of public green areas of urban area and in use of the categories to green public areas that fulfill the functions structural, legal and ecological. The used procedures identify a geometric figure for each public green area in wich benefit proportionate to the same one are quantified in terms of Density Green Areas (DAV),as direct result of relation surface of green areas (m²) and the surface area of distribution benefits (km²). In a subsequent stage, the density of green areas(m²/km²) was divided by population density (inhabitants/km²), resulting in Index Public Green Areas (m² green area/inhabitants). The applied procedures consider the distribution of proportionate services to the public green areas in the urban space, allowing determine the alterations in values of IAVP function of localization and the categories of public green areas.
