中文摘要：

城市街道的夏季微气候影响步行者的舒适感。在成都宽窄巷子的测试证明,街道的微气候波动规律与场地特征密切相关,街道设计会缓和或加剧气候对场地的影响。在有乔木遮蔽的街道上,设置喷雾能够降低空气温度,但加湿作用过强,不能有效改善舒适度。提出植物配置、铺装材料选择等风景园林设计策略,通过提供遮阳、调节通风和控制热辐射,创造舒适的步行街道。

英文摘要：

The microclimate environment in summer impacts the pedestrian＇s comfort on the street. A summer thermal environment survey was conducted in Kuan Zhai Alley in Chengdu. The result shows the diurnal pattern of microclimate was related to the character of the street. Differences in street design would mitigate or aggravate the impact of climate. In the street with heavy shadow of arbors, setting mist cooling could reduce the air temperature, but it enhanced the relative humidity largely. This strategy failed to improve the environmental comfort effectively in the end. When designing a pedestrian street, landscape architects should incorporate design strategies, such as planting arrangement and choosing appropriate pavements, to provide shade, adjust ventilation, control radiation, and finally create a comfortable environment.
