Urban heat islands and the transformation of Singapore

An urban heat island is defined as an urban area that experiences warmer temperatures than its surroundings. This study examines how Singapore's planning efforts established after the mid-20th century have affected the thermal environment of the city in association with land transformation, using historical temperature data available from the Meteorological Service of Singapore and some historical studies. Singapore's planners have carefully regulated the growth of its downtown while promoting expansion in other parts of the city-state. These effects of planning have also unconsciously shaped the location and outline of Singapore's urban heat island. As a result, new urban heat peaks were found around the centres of newly constructed large-scale new towns compared to industrial areas. This study provides lessons for land planning in mitigating a city's urban heat island effects. ?? ????????????????????????????????????????????????,??????????????????????????????????????????????????????????????,???????????????????????????????????????????,??????????????????????????????????????????????????
