中文摘要:
      针对夜间光照会对植物光合节律造成影响,提出了园林植物光合节律对城市夜景照明光照响应的研究;利用园林植物学与建筑光学的研究方法,选择城市夜景照明夜间光照常用的5种LED(Light Emitting Diode)光源光谱的3个光照强度进行园林植物实验;利用生物仪器监测园林植物白天与夜晚的净光合速率、气孔导度、蒸腾速率等光合节律数据,分析园林植物光合节律对夜间光照的响应;结果得出园林植物光合节律对夜间光照有积极的响应,且最终植物夜间光合节律数值高于未受人工光照前的数值;夜间园林植物光合节律的响应随夜间光照强度的增强而增强;受夜间光照的园林植物日间光合节律有上升趋势;蓝紫光、黄光、白光光谱的光照可促进园林植物光合节律的响应;结论得出园林植物光合节律对夜间光照的响应趋势,有助于掌握城市夜景照明与城市环境间的关系,控制夜间光照对城市环境的影响。
英文摘要:
      In view of the influence of nocturnal light note on plant photosynthetic rhythm,the response of garden plant photosynthetic rhythm to nocturnal light was studied.Using the research methods of landscape botany and architectural optics,the experiment was carried out with three kinds of light intensity of five kinds of LED light sources commonly used at night,and the response of photosynthetic rhythm of garden plants to light was monitored.These data include net photosynthetic rate,stomatal conductance,transpiration rate,etc.The results showed that the photosynthetic rhythm of garden plants had a positive response to the light at night.The value of photosynthetic rhythm at night was higher than that before artificial light,and the value of photosynthetic rhythm in daytime was increasing gradually.The stronger the light intensity at night,the more positive the response of photosynthetic rhythm.The response of photosynthetic rhythm of garden plants was promoted by the light of blue violet light,yellow light and white light spectrum.The conclusion is that the response trend of photosynthetic rhythm of garden plants to nighttime light and the influence of nighttime light on urban environment can be grasped.This conclusion can be used to control the damage of night light to urban environment.
