摘要:
道路照明系统及道路绿化系统是城市道路环境中2个重要的组成部分,两者之间既有密切联系,又相互独立。以郑州为例,分析了行道树与道路照明两者之间的相互影响。首先,利用照度仪分析了道路夜间照明的光环境特征以及行道树对照明效果的影响,结果表明,行道树位置分布及空间结构在一定程度上影响了夜间照明的效果及品质。其次,采用LI-6400XT光合仪对不同照明类型下(高压钠灯与LED灯)行道树光合生理参数进行观测,结果表明,不合理的夜间照明会对植物的生理生态产生负面影响。通过实验研究,提出了优化道路照明系统及绿化系统两者关系的调控策略及建议,试图为城市道路绿化及照明设计提供了有价值的参考及科学依据。

Abstract:
The road lighting system and the road greening system are two important parts in the urban road environment. Both are closely linked and independent. In this paper, taking Zhengzhou for example, the interactive influence between the road trees and road lighting are analyzed. First of all, the light environment characteristics of road lighting at night and the influence of road trees on lighting effect are analyzed with illuminometer. The research results show that the location, distribution and spatial structure of the road trees affect the lighting effect and quality at night to some extent. Secondly, the photosynthetic physiological parameters of road trees under different lighting types (high pressure sodium lamp and LED lamp) are observed and compared using Li-6400xt photosynthetic instrument. The research results show that unreasonable night lighting can have a negative effect on the physiological ecology of plants. Through the experimental study, the control strategies and suggestions are put forward for optimizing the relationship between road lighting system and greening system. This study tries to provide valuable reference and scientific basis for urban road greening and lighting design.
Key words:  landscape plant  road tree  road lighting  road greening  interactive influence
