To construct the index of urban environmental quality of public green areas of the city, adapted from the Genebrino or Distancial method (Sliwiany, 1997) using the PGAI and PPGA indicators (Equation 3), establishing threshold values by averaging the best and worst situations found the ARs.
The total PGAI obtained for the county was 18.85 [m.sup.2]/inhabitant.
This method applied to PGAI (GPGAI) showed satisfaction rates among different ARs (Figure 1).
The AR-01, despite covering a relatively small area (366.30 ha) compared to other ARs, concentrated 22 districts and a population of 15,530, with a VAP of 3.79%, resulting in PGAI of 8.94 [m.sup.2]/hab, considered bad, according to the classification presented in Figure 2.
With less land occupation, the AR-04 aggregates 7 neighborhoods, with a density of 9,847 inhabitants, has the lowest PGA (1.88%) and PGAI 6.44%, considered low.
The disparity between the PGAI 19.70 [m.sup.2]/hab, satisfactory, and PGA of 3.74% can be attributed to the low population density (19 inhabitants / ha).
Even with a PGA rated as "good" (8.65%), due to the high number of inhabitants (33,644), presented the PGAI [m.sup.2]/hab of 16.18 and 37.37% GPGAI, both classified as "regular".
The intermediate size of its land area (425.8 ha) and the average population density of 52.39 inhabitants / ha resulted in PGAI [m.sup.2]/hab 17.72 and 42.17% of the Genebrino, classified as good.
