Microclima urbano e as áreas verdes: estudo de caso do Parque Arnulpho Fioravante, Dourados, MS

Abstract

The daily pressures exerted by the urban centers, added to the absence of green areas, end up promoting great damages to the quality of life of the resident population. The objective of this work is to evaluate the influence of a green park in the center of the city of Dourados (MS) in the thermal and sound comfort through environmental indicators. The air temperature (° C), relative air humidity (%), luminous incidence (LUX) and noise variation (dB) were measured at sample points in the Arnulpho Fioravante green park and adjacent areas. It was also adopted the Thermal Discomfort Index (TDI), which takes into account the variables temperature and relative humidity of the air. The TDI and noise results indicated that the park has little influence on adjacent areas. On the other hand, the area of greatest plant density (park reserve) presented significant values of TDI, classifying it as "feeling comfortable" and "feeling partially uncomfortable". On the other hand, the areas of the city and the park without vegetation presented many classifications "feeling uncomfortable". It was also observed that the vegetation may have acted as a filter to minimize urban noise. Our results indicate that urban green areas are important components in the quality of life of the population, provided that it has a good planning and management of available forest resources.
