浅析夜景照明对植物生长的影响

Night Lighting Effects on Plant Growth

文章首先简述了城市夜景照明的概念及城市主要绿化植物的种植和分布,依据城市空间分布将夜间照明和城市植物进行了简单划分,以光源为出发点,归纳了光照(光质、光时和光强)在植物光合作用、生长代谢等方面的作用。综合分析了当前国内外在该方向的研究进展,指出了目前城市夜景照明和城市绿化植物两者之间相互结合相对欠缺的研究现状。提出了具体化研究想法:采用实地调查及试验方法统计分析夜景照明对城市绿化植物的现状,并以新型光源LED为入手点将两者结合研究。最后,对合理安排规划城市夜景照明和保护绿地植物提出意见。

Firstly, we introduced the concept of urban night lighting and common urban greening plants; then, according to urban spatial distribution, we divided the night lighting and urban plants into different categories; finally, using the light source as the starting point, we summarized the plant growth and metabolism in photosynthesis under the light treatments （lighting quality, lighting time or lighting intensity）. The current domestic and foreign research progresses in this field were analyzed and the relative deficiency of research on current urban landscape lighting and urban greening plants was pointed out. In conclusion, we put forward suggestions as using field survey and experiments to understand the influence of night lighting on urban greening plants, taking into consideration of the new light source LED, and arranging the urban lighting design for protecting urban greening plants.
