The urbanization has been provoking local variations in several climatic elements, among
them it a increase of the temperature of the air, provoking the emergence of portions of the
space with larger temperatures than the areas to yours spill, that calls her of urban islands of
heat. Among the causes of the appearance of the islands of heat, the retreat of the vegetable
covering is the most relevant. The purpose of this work was to identify, through the technique
of remote sensing, the urban islands of heat and the urban islands of coolness in the
continental area of the Municipal district of Belem, as well as the variation of the vegetable
covering, comparing the results of the years of 1997 and 2008, in order to reveal a possible
relationship between the variation of the vegetable covering and the islands of heat and urban
islands of coolness. To develop this research, it was fallen back upon thermal images of
sensor TM for determination of the temperature values, as well as data of temperature of the
air observed in the stations: climatological conventional of Belem (2o. DISME / INMET),
meteorological sinotic of Val-of-Cans and meteorological automatic sinotic of Belem (2o.
DISME / INMET). The vegetable covering was also determined with use of the images of
sensor TM, with the bands 3,4 and 5. In agreement with the obtained results, it was ended that
there was an increase of the urban islands of heat in 2008, mainly in the located
neighborhoods in the areas of the Avenue Augusto Montenegro and Highway Arthur
Bernardes, and reduction of the islands of coolness in several parts of the continental area of
Belem, due to the absence of the vegetable covering, in relation to the year of 1997. It was
also possible to identify that in the study area, there was a reduction of the existent vegetable
covering in 2008 in comparison with 1997, reduction that that happened mainly in the area
that is besides to 1st Patrimonial League of the municipal district of Belem, in the axis
understood between the Avenue Augusto Montenegro and the Highway Arthur Bernardes,
enlarging the urban area and the increase of the temperature, that it favored the expansion of
islands of heat.
