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