| 针对城市照明会影响植物花果期物候的变化,提出园林植物与照明关系的研究;利用跟踪观测的方法,记录被照植物生长环境,计算被照射植物的花期及生长季,并与文献记载植物花果期进行比较,研究夜景照明与园林植物花期果期的关系;得出人工光照是影响绿化植物花期与果期的直接因素,园林植物花期可作为人工光照对植物物候影响指示器;受人工光源照射的园林植物花期变化相对明显,展叶期变化也相对明显,乔木花期对人工光照反应较为弱;落叶植物花期对人工光照敏感,夜间光照下落叶乔木果期提前,花期延长;园林植物花果期对 LED 白光、黄光光谱照射较为敏感;指出得出深入对城市光环境与绿化植物花果期影响的研究,可有效掌握受人工光照下的园林植物花果期的变化规律,对预测园林植物生长、保护生态环境、指导园林夜景建设有重要的意义。 |

| Abstract: |
| In view of the influence of urban lighting on the phenology of plants in the flowering and fruiting stage, a study on the relationship between garden plants and lighting was proposed. The relationship between nightscape lighting and flowering and fruit period of garden plants was explored by using the method of tracking observation, recording the growth environment of the illuminated plants, calculating the flowering period and growing season of the illuminated plants, and comparing them with the flowering and fruiting periods of the plants recorded in the literature. The results showed that artificial light is the direct factor affecting the flowering and fruiting stages of greening plants; the flowering period of garden plants can be used as an indicator of the effect of artificial light on plant phenology; the flowering period of the garden plants irradiated by the artificial light source is relatively obvious, and the leaf-expansion period is also relatively obvious. Trees have a weak response to artificial light during flowering. The flowering period of deciduous plants is sensitive to artificial light, and the fruiting period of deciduous trees is earlier and the flowering period is prolonged under the night light. And garden plants are more sensitive to LED white light and yellow light spectral irradiation during the flowering and fruiting period. It is concluded that an in-depth study on the influence of urban light environment on the flowering and fruiting period of green plants can effectively grasp the changing law of the flowering and fruiting period of garden plants under artificial light, which is useful for predicting the growth of garden plants, protecting the ecological environment, and guiding the construction of garden night scenes. |
