Evaluation of urban light-emitting diodes lighting facilities’ impact on landscape shrub

Abstract

In the field of urban lighting and landscape planning, most researchers focus on how to make lighting meet people’s demand, while few researchers consider the impact of lighting systems on landscape plants. Based on statistical methods and field measurements, the brightness data of street lamps in a street of Shanghai were collected, and these data were compared to the shrub growth data of the street green belt. The results show that LED street lighting facilities have a promotion effect on the growth rates of shrub’s new shoots, while it also have effect on shrub leaves’ greenness. This study discussed a statistically method to evaluate the impact of urban lighting system on landscape plants, providing theoretical and methodological support for unban lighting and ecological landscape design. Besides, this study could also help further study about the impact of urban lighting on Urban ecosystem.
