摘　　要：城市夜景建设促进了夜间景观多样化及文旅经济的发展,在吸引游客的同时也对当地居民造成了一定程度的光污染干扰。如何展开光环境评价以精准识别不同使用主体的光环境需求,成为构建城市健康光环境的关键。文中以文旅与“夜经济”协同发展的西安曲江新区为研究对象,针对游客、居民的照明需求差异,基于POI数据的重分类与赋值将曲江新区照明空间划分为4类照明分区,从光健康、光舒适、光艺术表现力3个层次构建主客观相结合的光环境评价模型,分别对4类分区进行综合评价。结果表明:照明冲突区游客、居民在光舒适体验方面差异显著;照明协调区、特色区各项实测数据较为均衡,能满足居民及游客的需求;照明控制区各项实测数据均明显低于其他区域,整体满意度最低。研究结果说明基于POI数据的照明分区可以为城市夜间光环境评价提供精准指导。Urban nightscape construction promotes the diversification of night landscape and the development of culture-tourism economy,which attracts tourists but also interfere local residents with a certain degree of light pollution.How to accurately identify usersneeds for light environment through the evaluation has become the key to building a healthy urban light environment.Xian Qujiang New District is where cultural tourism and“night economy”have been interactively developing.In view of the different demand of tourists and residents for lighting,the paper divides the lighting space of Qujiang New District into 4 types of lighting zone based on the reclassification and assignment of POI data,and the light environment evaluation model featured with subjective-objective combination is constructed from the 3 levels of light health,light comfort,and light art expressiveness,with which the 4 lighting zones are evaluated.The results show that there is a significant difference in the light comfort between tourists and residents in the lighting conflict zone,and the measured data in the lighting coordination zone and the featured zone are more balanced,which can satisfy the needs of residents and tourists.The measured data in the lighting control zone are significantly lower than in other zones,showing the lowest overall satisfaction.In summary,it can be seen that the lighting zoning based on POI data can provide accurate guidance for evaluating the light environment in urban nightscape.
