Análise da influência da vegetação arbóreano comportamento térmico dos diferentes tipos de revestimento do solo

Abstract

The planning of trees in cities is necessary and indispensable as it directly affects the thermal comfort and quality of life of the inhabitants. Currently, the growth of population in cities has led to changes in natural landscapes and waterproofing in urban areas. The objective of this research was to analyze the influence of trees on the

thermal behavior of different types of land cover (asphalt, concrete and soil) in hot- dry periods and hot-humid in the city of Cuiaba-MT. Were chosen two abundant tree

species and typically used in the region: mango tree (Mangifera indica) and oiti (Licania tomentosa). As reference was used a place without tree shading with these same land cover to determine which of the species studied is the most suitable to provide reduction in the thermal environment. The data collected were leaf area index, internal temperature and surface materials, temperature and humidity. Questionnaires close to points of data collection were performed for three shifts (morning, afternoon and evening) and it was verified the contents of thermal comfort through the PMV (Vote Estimated Average) and PET (Physiological Equivalent Temperature) in RayMan software. The results show that land cover installed under the species of canopy mango tree (Mangifera indica) got the best internal thermal performance. The soil had the best thermal performance internally and superficially. The air temperature showed a significant reduction of local shaded by tree species in relation to the site without tree shading. Therefore, it is worth noting the importance of trees in cities to provide better thermal comfort for users, especially in hot climate regions.
