碩士 === 淡江大學 === 建築學系碩士班 === 100 === This study is aimed to explore to the heat island effect around Minzu W. Rd, Datong Dist, Taipei. By survey of the station and to simulation airflow and temperature field , to find out where is the potential area. Aim each area to recommend proper tactic of reduce the urban heat island, and aimed the tactics to simulation to know each Improvement benefit. Compared to those Improvement benefit in order to suggestion the better tactic of reduce the urban heat island in this station. These tactics can give following research and urban design for reference. Outline of each chapter： Chap.1- Describing the motive, purpose, scope configuring flow and methodology of this research. Chap.2- Discusses the theory of urban heat island effect, and than discusses the principle of heat radiation characteristics of objects, common fluidic phenomena in urban. Explore the influence of local climate. Finally, to analyze foreign tactics of reduce the urban heat island. Chap.3- Researching the geographical environment of the Taipei City, Datong District, and Minzu W. Rd, then study the climatic characteristics of Taipei, investigate the site status, Identify potential areas of reduce the heat island. Integrate the Central Weather Bureau''s data and local Climate station''s data to be the research background. Then introduction software. Integrating Ecotect, Stefan-Boltzmann law and phoenics, and the proceed to the CFD simulation of present situation. Chap.4- In accordance with the conditions of the potential areas to develop the tactic of reduce the heat island. The main strategic direction is：(1)Green Belt policy (2)Blue Belt Policy (3) Building shell improvements (4) Ventilation cooling (5)Ground cover material improvement. According to the above five strategies develop 12 models, and proceed to the wind, temperature simulation. Chap.5- Compare the results of simulation, and weighted assessment of the strategy. Chap.6- Summarize the conclusions of this study: (1) Analysis the wind and temperature conditions in the urban by integrating Ecotect,Stefan-Boltzmann law and phoenics ,can be used to study the urban heat island effect. (2) Increase the urban green space could improve the urban comfort . (3) The density of building ,arrangement and building spacing of block is the key point for ventilation. (4) Should be increase the plants cover rate of urban space as a principle to improve the comfort in the long run.
