Abstract: A large number of climate-adaptive strategies are a part of the traditional urban settlement, which is significant for guiding modern urban climate design. This research focuses on the traditional Arcade-street neighborhood, which is distributed widely in the hot and humid climate zone in south China, and attempts to investigate the characteristics of climate adaptation in these neighborhoods. A series of in-situ measurements and simulations of the pedestrian thermal environment in different types and scales of the street canyon were conducted in Kaiyuan District (Xiamen) and Enning District (Guangzhou) in the summer season. Furthermore, the Physiological Equivalent Temperature (PET) was used to evaluate pedestrian thermal comfort. A better self-shading effect existed in the differently oriented alley of the Xiamen neighborhood with an organic form, as illustrated in the results of this study. In contrast, the E-W oriented street in Guangzhou with a band fabric had an unbearable thermal environment. Meanwhile, the thermal environment of the pedestrians in the arcade maintained a relatively steady PET for varying outdoor environment backgrounds, benefitting from arcade shading, but the effectiveness was related to the orientation.

Key words: hot and humid climate zone, traditional arcade-street neighborhood, street canyon microclimate, in-situ measurement, thermal environment simulation.

摘要： 城市传统聚落蕴含丰富的地域气候回应策略，并对指导现代城市的气候设计有重要意义。通过对湿热地区中广泛分布的传统骑楼街区进行热环境实测与模拟，在人体热舒适评价的基础上，分析城市传统聚落的气候适应性特征。以厦门的开元路街区以及广州的恩宁路街区为例，比较不同城市形态以及不同街谷中的热环境分布情况。发现有机形态布局下的厦门街区可以在不同朝向的窄巷中实现较好的热环境，而规整条状布局的广州街区中的东西走向的窄巷则很难形成有效的建筑自遮阳；同时骑楼覆盖下的人行区内可以维持相对稳定的热环境，但其对热环境优化的效果与街谷朝向有较大关联性。
