【摘要】 热岛效应是城市面临的主要问题,城市居住区采用不同的下垫面材料会引起温度的分布差异。研究者应用实地测试的方法对中国西安曲江宜居小区的室外温度进行了研究,测试对象包括水体、植物、架空层、建筑物天井、下垫面材料等室外常用的形式。测试结果表明松树的降温效果较好,天井和架空层的降温能力较好,小范围的水体降温能力有限,铁质材料的升温快,降温也快,晴天、雨天等天气状态对居住区温度具有显著的影响。更多还原

【Abstract】 The urban heat island effect is the main problem facing the city. The use of different underlying materials in urban residential areas will cause temperature differences. The researchers applied field test to study the outdoor temperature of the Qujiang Yiju Community in Xi’an, China. The test objects included outdoor forms such as water bodies, plants, open floor, building patios, and underlying surface materials. The test results show that the cooling effect of the pine tree is better, the cooling ability of the patio and the open floor is better, the cooling ability of the water body in a small range is limited, the heating of the iron material is fast, and the cooling temperature is also fast. The weather conditions such as sunny days and rainy days have a significant impact on residential temperature.更多还原
