摘要
我国湿热地区夏季空气温度和湿度相对较高,太阳辐射强烈,人们在此种气候条件下的室外步行商业街区活动可能会造成身体不适,甚至是中暑。因此,高品质的室外热环境既对于步行商业街区在吸引人流方面扮演了重要角色,同时也为城市公共空间提供活力。通过对南宁市典型步行商业街区夏季室外热环境变量进行测试,从而得出热环境与周围材质和建筑类型有关,遮阳形式是决定人在步行通道空间中是否感到舒适的重要因素。
In hot and humid areas of China, air temperature and relative humid were relatively high in summer, as well as the solar radiation. Hot and humid weather conditions may cause pedestrians uncomfortable and even heat stroke walking on the urban pedestrian streets. So, the thermal quality of outdoor environment on urban pedestrian streets not only plays an important role to attract business around these pedestrian streets, but also provides vitality for urban public space. In this paper, the field measurement of outdoor thermal environment on the typical pedestrian streets in Nanning in a typical summer day. The measurement results reveal characteristics of the thermal environment on the investigated pedestrian passages due to different surrounding materials and building forms. It is concluded that effective sun-shading is the key factor to determine whether the pedestrians feel comfortable on the pedestrian passages in the hot-humid climate.
