Análise de áreas verdes urbanas em Patos, Paraíba.

Abstract

The urban green areas contribute to better environmental quality of life in cities because of the many functions that can exert. This study aimed to analyze the conditions of green areas in the central city of Patos and in the Municipal Park, and generate a percentage of cover crops evaluated. The study was performed at Edivaldo Motta, Alcides Carneiro and Getulio Vargas Squares and in the Religious Park Cruz da Menina. The individual trees in each area were evaluated quantitatively (height, diameter and circumference at breast height) and qualitatively regarding physical and health characteristics and areas. Based on the data, we calculated the percentage of vegetation cover and realized the physical and qualitative analysis of the areas. In Edivaldo Motta square 31 individuals were identified, distributed among eight species being approximately 71% native, 23% subspontaneous and 6% exotic. In Alcides Carneiro square 41 individual trees were identified, distributed in nine species, about 76% of individuals were classified as native, 5% subspontaneous and 19% exotic. In the Vargas square we identified 24 individual trees, subdivided into six species, of which approximately 67% were Native, 4% subspontaneous and 29% exotic. In the Religious Park Cruz da Menina, there were 158 trees, distributed in 16 species, classified as 20% native individuals, 51% subspontaneous and 29% exotic. Overall, it was found that most of the individuals found in areas showed good physical appearance and health, with the exception of those in the Religious Park Cruz da Menina, where there are individuals with bad aspect and dead. In Vargas square we found a higher percentage of vegetation cover (86.48%), whereas the Religious Park Cruz da Menina presented the lowest canopy (29.59%). The four areas studied showed a high environmental quality. With a tendency to homogeneity when in good physical and environmental conservation.
