Natural photic regime has been drastically altered by the artificial night sky luminance. Despite evidence of sufficient light brightness inducing plant physiology and affecting phenology, generalization regarding effects of light pollution on plant phenology across species and locations is less clear. Meanwhile, the relative contributions and joint effects of artificial light pollution and climate change or other anthropic stressors still remain unknown. To fill this knowledge gap, we utilized in situ plant phenological observations of seven tree species during 1991–2015 in Europe, night-time light dataset and gridded temperature dataset to investigate the impacts of the artificial light pollution on spatial-temporal shifts of plant phenological phases under climatic warming. We found 70% of the observation sites were exposed to increased light pollution during 1992–2015. Among them, plant phenological phases substantially delayed at 12–39% observation sites of leaf-out, and 6–53% of flowering. We also found plant species appeared to be more sensitive to artificial light pollution, and phenology advancement was hindered more prominently and even delay phenomenon exhibited when the color level showed stronger sky brightness. Linear mixed models indicate that although temperature plays a dominant role in shifts of plant phenological phases at the spatial scale, the inhibitory effect of artificial light pollution is evident considering the interactions. To our knowledge, this study is the first to quantitatively establish the relationship between artificial light pollution and plant phenology across species and locations. Meanwhile, these findings provide a new insight into the ecological responses of plant phenology to the potential but poorly understood environmental stressors under this warmer world and call for light pollution to be accorded the equal status as other global change phenomena.

人造夜空亮度极大地改变了自然光状态。尽管有足够的光亮度诱导植物生理和影响物候的证据，但关于光污染对跨物种和地点的植物物候影响的概括还不太清楚。同时，人工光污染与气候变化或其他人为压力因素的相对贡献和联合效应仍然未知。为了填补这一知识空白，我们利用 1991-2015 年欧洲七种树种的原位植物物候观察、夜间光数据集和网格化温度数据集来研究人工光污染对植物物候时空变化的影响。气候变暖下的阶段。我们发现 70% 的观测点在 1992 年至 2015 年期间暴露在增加的光污染中。其中，植物物候期在 12-39% 的出叶观察点和 6-53% 的开花期显着延迟。我们还发现植物物种似乎对人工光污染更敏感，当颜色水平显示出更强的天空亮度时，物候进展受阻更明显，甚至出现延迟现象。线性混合模型表明，虽然温度在空间尺度上植物物候阶段的变化中起主导作用，但考虑到相互作用，人工光污染的抑制作用是明显的。据我们所知，这项研究首次定量建立了跨物种和地点的人工光污染与植物物候学之间的关系。
