摘要
城市热岛效应是城市的病态气候现象，潜在的危害极大。从广州的亚热带城市气候资源水平出发，讨论了应用城市气候资源的自我调节机制改善城市热环境的方法，目的在于减弱广州的城市热岛效应。广州地区利用被动蒸发冷却技术可获得建筑屋面的最大温差为10℃，平均温差为5℃。分析认为，广州地区因为具有完整的气候要素，具备依靠被动蒸发冷却技术实现城市非绿地表面被动降温的自然条件。文中还提出了广州城市气候资源应用研究方面的5项主要课题。
Heat island' effect is an abnormal urban phenomenon with great potential harmfulness. A method ofinproving the urban thermal environment of Guangzhou by application of selt-control of Seif coed system of dri clhacso is discussed. The ppe of the study is to witipe the hod island dst of Guangzhou. It is shownthat sdse tempeture of building roofe can be reduced by 10℃ in for and 5 ℃ on aerag by usingthe tecndqUe of passive ereling driugh evaporahon. It is considend that the subtcal clirnae ofCuwtou provides natural conditions for passive eding in non-mp us by the tecndque. Finally, fiveapplied research projects of urban climatic resoarees in Guangzhou City are suggested.
