摘要:Urban heat island is a phenomenon that urban have higher temperature than surrounding area. Factors that influence the temperature consist of factors that can be controlled by humans, including the city design and structure, total population , and factors that can not be handled by human, like season, cloud cover, and atmospheric dynamics (Rizwan et al., 2008). The purposes of the study were to determine urban heat island in Yogyakarta and its surrounding area, temperature range, and the role of land cover to the temperature. Urban heat island type that identified in this study was surface urban heat island. The heat island was obtained from interpretation of Landsat Imagery catched on September 12, 2013. This image were used to determine the type of land cover beside temperature. Heat island occurred at Yogyakarta and surrounding area. The heat focused in Yogyakarta City and extended to the north-east of the city. Range the temperature were 5 up to 10°C. Land cover associated with the low temperature was vegetation while the land cover associated with high temperature was building area.
