Uso Do Solo E Temperatura Superficial Em Área Urbana

Abstract: Este estudo avalia a ilha de calor da superfície urbana e a relação espaço-temporal entre o uso da terra e a temperatura da superfície (Ts) na cidade de Várzea Grande, que juntamente com Cuiabá (capital do estado) formam um dos maiores conglomerados da região Centro-Oeste do Brasil, cujo processo de urbanização tem sido intenso desde a década de 60. Utilizou-se neste trabalho imagens multiespectrais do satélite LAN-DSAT-5 TM para elaborar mapas de uso e ocupação do solo e de temperaturas superfi ciais (Ts) e d… Show more

“…The average monthly net radiation in February presented the highest values for slab and simulated green roof (29.47 and 12.98 MJ m −2 day −1 , respectively) ( Figure 7). In general, Rn values are slightly higher when compared to those observed in adjacent rural regions due to the combined effect of short-and longwave radiation (Callejas et al, 2012). Brest (1987) pointed out that the presence of vegetation in urban areas reduced net radiation on the surface mainly because the effective albedo of a vegetated surface was higher than that found on a surface without vegetation.…”

“…Ao comparar o mapa de Geotecnologias: aplicações no campo interdisciplinar distribuição da Ts com o mapa das características de uso e cobertura da terra, tornou-se possível visualizar que as maiores cotas de Ts referentes às ilhas de calor no espaço urbanizado de Belém, encontravam-se associadas às classes com maior teor de antropização. Resultados similares também são observados em trabalhos de Coelho (2013), Callejas et al (2011), Costa et al (2009 e Pires e Ferreira Jr (2015),…”

“…Studies have reported that the reduction of green areas and soil waterproofing, due to the urbanization process of the cities, contribute to the increase of air temperature (AMORIM et al, 2009;AMORIM, 2010;ROCHA et al, 2011). Callejas et al (2011) verified that there was an increase of more than 2.13 °C of surface temperatures in urbanization areas in the city of Várzea Grande (MT) between 1986 and 2007.…”
