    Key words:landscape plants; landscape illumination; leaf color; spectral energy distribution; illumination intensity

    摘要:园林夜景照明在全国广泛开展, 滥用光照干扰了植物的生物节律,影响了植物叶片呈色与造景色彩。通过对重庆8个区域照明对植物叶片色影响的调研和光照测量,并对4种常用光源光谱的检测,研究了人工光照对植物叶片色的影响,得出高压钠灯和金卤灯大部分光谱对植物叶片色影响小,白光LED及荧光灯因蓝光光谱对叶片色影响大的结论。建议了适合园林植物色彩保护的照明参数,并用照明技术解决因天然光照不足产生的植物叶片色彩问题。

    Abstract:Garden nightscape developed widely in China, but the abuse of light disturbed the biological laws of plants and caused the change of the colors leaves. The research was conducted in Chongqing, which included the effect on colors of plant leaves based on the measurement of illumination of landscape lightning in 8 areas. With the measurement analysis of intensity of four artificial lights and spectral energy distribution, the rule is worked that the colors of leaves of garden plants change with the alteration of artificial lights, and LED lighting interferes the plants mostly while HPSL and MHI the least. The paper tries to use landscape illumination technique to deal with uneven plant colors, and offer technical parameters of landscape illumination based on landscape ecology.
