世界上所有城市的气温都在逐渐上升。其中一个可能的原因是城市绿化面积的急剧减少。本研究旨在探讨土地利用类型对新加坡环境温度升高的影响。主要工具是遥感数据和地理信息系统（GIS），以获得新加坡的宏观视图，同时进行综合分析。采用定性和定量相结合的方法对数据进行分析，定性和定量分析结果均表明土地利用对城市温度有影响。白天，不同土地利用类型地表温度由高到低依次为工业、商业、机场、居民区、公园。然而，在夜间，顺序是商业，住宅，公园，工业和机场。因此，通过合理的土地利用规划，可以缓解城市热岛效应。(C)2007爱思唯尔有限公司保留所有权利。
The urban air temperature is gradually rising in all cities in the world. One of the possible causes is the drastic reduction in the greenery area in cities. It means that land use planning becomes critical in determining the environment quality.This study tries to investigate and identify land use types which have the most influence to the increase of ambient temperature in Singapore. The main tools are remote sensing data and geographical information system (GIS) to obtain a macro view of Singapore and carry out comprehensive analysis at the same time. The data were analyzed by utilizing both qualitative and quantitative methods.Both the qualitative and quantitative analysis results show that the land usage will influence urban temperature. In the daytime, the order of surface temperature in different land use types is industrial, commercial, airport, residential, and park respectively. However, during the night time, the order is commercial, residential, park, industrial, and airport. Therefore, with appropriate land use planning, the urban heat island (UHI) could be mitigated.
