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.

城市热岛与新加坡的转型

城市热岛被定义为温度高于周围环境的城市地区。本研究利用新加坡气象局提供的历史温度数据和一些历史研究，探讨了新加坡 20 世纪中叶后制定的规划工作如何影响与土地改造相关的城市热环境。新加坡的规划者在促进城市国家其他地区扩张的同时，也小心翼翼地规范了市中心的发展。这些规划的影响也在不知不觉中塑造了新加坡城市热岛的位置和轮廓。因此，与工业区相比，新建大型新城中心周围出现了新的城市热峰。这项研究为缓解城市热岛效应的土地规划提供了经验教训。
