THE INFLUENCE OF THE DIFFERENT TYPES OF URBAN FOREST IN THE IMMEDIATE SURROUNDING MICROCLIMATE

摘要

The urban forest generates a microclimate more pleasant for the human being, in its interior as in the near external areas. Thus, the main goal of this research was to analyze the influence that the different typologies of urban forest exert in their immediate surrounding, highlighting quantitatively the differences between the internal and external microclimate to these areas. For this, areas of different types of urban forest were selected in the city of Curitiba-PR: Remaining Forest, Old Green Area, Modern Green Area, Street Trees and Isolated Tree. The influence in the immediate surrounding was analyzed with the mobile transect method, traveling 500 m away from a street adjacent to the selected area, with data collection every 50 m. The results indicate statistical differences between the internal and external microclimate to the typologies of urban forest. During the transect, the temperature was on average 2.3 ° C higher than in the interior of the urban forest typologies, the relative humidity was lower in 4.6 units and the wind velocity 0.2 m / s higher. The greatest difference in temperature and relative humidity between the internal and external environment was found in the Remaining Forest and the smallest in the Street Trees. It is concluded that the different typologies of urban forest exert a significant influence on the immediate surrounding microclimate.
