山地城市居住区室外夜间光环境调研与策略优化——以重庆市主城区为例

Investigation and Strategy Optimization of Outdoor Nighttime Light Environment in Residential Area of Mountainous City——Take the Main District of Chongqing City as An Example

我国山地城市量多面广,居住区室外空间多有陡坡和台地,而针对性的夜间光环境研究却缺乏。近年来居住区的开发和更新模式变化大,其室外夜间光环境的供求也随之变化,适时对其进行调研,对居住区室外夜间光环境现状的研究十分必要。通过对重庆主城区六个典型居住区室外夜间光环境进行调研,包括地方道路和台阶区域照明参数的监测以及主观问卷调查,结合相关标准,分析了我国山地城市居住区室外夜间光环境的现状和问题,提出了相应的光环境优化策略。

There are many kinds of mountainous cities in China,and the outdoor space of residential areas is mostly steep slopes and terraces,but there is no targeted study of light environment at night.In recent years,the development and renewal mode of residential areas has changed greatly,and the supply and demand of outdoor nighttime light environment has changed correspondingly.It is necessary to investigate the outdoor nighttime light environment of residential areas in time.Through the investigation of outdoor night light environment in six typical residential areas of Chongqing main urban area,including the monitoring of local road and step area lighting parameters and subjective questionnaire survey,combined with relevant standards,the paper systematically analyzes the status and problems of outdoor night light environment in residential areas of mountainous cities in China,and puts forward corresponding optimization strategies.
