Resumo: |
The phenomenon of urban heat islands is directly related to human activities and the type of materials and equipment used in the expansion of the urban fabric (concrete, asphalt, roofing, etc..), Which absorb and retain heat from sunlight, mainly because it is not just used to process Evaporative which certainly feeds the increase in air temperature in cities. Thus, this study was to analyze and identify the phenomenon of urban heat island between urban areas of Recife-PE, from TM images Landsat 5. For the study was obtained images from orbit 214 points 65 and 66, the dates of 04/08/1998 and 06/09/2010. From the image processing were generated letters of the surface temperature, albedo and NDVI to the city of Recife and five selected districts (Pina Santo Amaro, Casa Amarela, Dois irmãos and Curado ), to analyze the dynamics of transformation occurring in area study. Through the profile developed for the study area was perceived to increase spatial and temporal surface temperature toward the center-suburbs, resulting in a difference of 6°C between these areas. Neighborhoods with urban concentrations, lots of buildings vertical and horizontal, stood out as those at higher temperatures, performing over 27°C, found in the districts of Casa Amarela and the Santo Amaro. In areas where there was a reduction of the vegetation index was an increase in surface temperatures around 3°C. The emergence heat islands can be attributed to following factors: concentration buildings which implies in increased temperature; energy production anthropogenic issuing heat coming industries, transits and dwellings; replacement vegetation by asphalt; radiation, caused by emissivity bodies. |
