城市公共开放空间光环境研究

Research on Luminous Environment in Urban Public Open Space

通过对常州市的商业广场、城市公共绿地、市政广场三类公共开放空间11个场所的平均水平照度、平均垂直照度、照度均匀度进行实测和分析,总结城市公共开放空间光环境的特点:商业广场的平均照度最高,市政广场的平均照度略高于城市公共绿地;较高的照度和较低的照度都容易形成较高的照度均匀度。

The average horizontal illuminance, average vertical illuminance and uniformity ratio of illuminance of 11 locations classified into the public open space including the commercial plazas, urban public greenbelts and municipal squares in Changzhou City are measured and analyzed, based on which the features of luminous environment of such space are summarized. An analysis of the data shows, i. e. commercial plaza 〉 municipal square 〉 urban public greenbelt. And it is also found that public open spaces, whether with higher or lower illuminance, tend to have high uniformity ratio of illuminance.
