摘要：http://dx.doi.org/10.5902/223611707705 This paper presents the results of a study that investigate the magnitude and extent of theinfluence of fragments of vegetated area on thermal environments of urbanized areas of the cityof Cuiabá, MT. The main tools were remote sensing, on examination of a CBERS acquired on June20, 2009, mobile measurements and geographical information systems to obtain a macro view ofurban complex. The results confirmed the influence of fragments of woody vegetation on the airtemperature environments analyzed, ranging between 200 m and 500 m, depending on the timeand station, dry or rainy. It was found that the fragmentation of green areas, described by thefractal dimension, acts more decisively in thermal environments with low percentages ofvegetated area, and in such cases a less fragmented vegetation resulted in lower air temperatures.
