摘要

Urban development is unavoidable as the result of country's economic growth. Without a careful planning, a city may cause environment destruction. Singapore is known to have the best environmental quality in the world. However, in the previous research on Singapore Urban Heat Island (UHI), it was found that UHI exists with intensity of 4°C difference between downtown area and nature reserve area. This phenomenon also exists in other countries and many researches have been done proofing its existence. It is because soil and trees are replaced with concrete and high rise building. This study is the extension of the Singapore urban heat island study which focuses more on the microclimate scale. National University of Singapore (NUS) Kent Ridge Campus was chosen for this study. In order to map out temperature condition, field measurement has been done on 26 August - 25 September 2006. It was found that at the dense greenery area along Kent Ridge Road, the temperature condition can be as low as 3.2°C as compared with sparse greenery area in Prince George's Park canteen during day time around 15.00. During night time the temperature difference can be 2°C around 3.00 - 4.00. It shows that urban heat island phenomena happened in NUS Kent Ridge Campus and greenery provides a good benefit to reduce the ambient temperature. All of the measurement data was put into the Geographical Information System (GIS) database system and then daily day time and night time temperature maps were produced. By using GIS, temperature profile across the NUS Kent Ridge campus can be generated to provide clearer picture about the temperature distribution and facilitate a further analysis.
