【摘要】 为掌握城市商业步行街热环境状况,对广西南宁市民生路商铺、街道环境和人行通道进行夏季热环境测试,采用定点定时连续测试方法。在白天10个小时中,选取商业步行街不同建筑朝向较具代表性的10个测点,测点多在骑楼下人行道。进行空气温度和相对湿度、黑球温度、地面温度的测试。通过对整个商业步行街道路遮阳和下垫面材质实地观察和测试数据分析,结合国内外城市建设成功经验,对今后商业步行街建设就街道热环境及购物环境舒适性等提出可行性建议。建议商业步行街除了机动车禁行及提供行人休息的椅子,还应考虑商业步行街行道树或景观树的选择、道路遮阳方式,以提供舒适的环境。更多还原

【Abstract】 In order to get a good understanding of the thermal environment on urban pedestrian streets,the authors have conducted summer measurements of the thermal environment at the selected points(near the stores,on the streets,in the pedestrian passageways) on Minsheng Road of Nanning,Guangxi Province.10 measurement points were selected for typical directions of different buildings on the urban pedestrian streets(mainly the sidewalks) in arcade building passages.The measurement recorded four sets of data for air temperature,relative humidity,black-bulb temperature and ground temperature during the10-hour period from 10:00 to 20:00 on sunny summer days.Based on the field observation of the shading effect of the pedestrian street and the thermal effect of the ground surface materials,analysis results of measurement data and successful experience of domestic and overseas urban construction,this paper proposes the following suggestions for the future urban pedestrian streets from views of thermal environment and shopping environment,etc.Besides forbidding motor vehicles and providing customers with benches for a rest,shopping comfortableness should be taken full consideration on an urban pedestrian street;roadside trees and landscape trees on the urban pedestrian street should be leafy so as to not only be conducive to provide a good rest place for pedestrians but also enable shops to have more sunshade and reduce energy use in air-conditioning.更多还原
