随着人造光的引入，地球表面在夜间经历自然黑暗环境的比例正在迅速下降。从基因到生态系统，以及各种各样的环境和生物体，都记录了这种变化的生物影响。这些影响的可能严重程度在很大程度上取决于夜间人工照明的分布与生物多样性之间的关系。在这里，我们进行了一个全球性的评估之间的重叠保护优先领域和最新的人工天光地图集。我们表明，在世界上的关键生物多样性地区（KBAs），不到三分之一的地区有完全原始的夜间天空，大约一半的谎言完全在人工明亮的天空下，只有大约五分之一的地区没有夜间天空没有被污染到顶点。KBAs的光污染程度因地区而异，影响欧洲和中东KBAs的比例最大。统计模型揭示了KBAs内的光污染与国内生产总值和人口密度的相关水平之间的关联。这表明，随着经济的持续发展和人口的增长，这些模式将进一步恶化。
The proportion of the Earth's surface that experiences a naturally dark environment at night is rapidly declining with the introduction of artificial light. Biological impacts of this change have been documented from genes to ecosystems, and for a wide diversity of environments and organisms. The likely severity of these impacts depends heavily on the relationship between the distribution of artificial night-time lighting and biodiversity. Here, we carry out a global assessment of the overlap between areas of conservation priority and the most recent atlas of artificial skyglow. We show that of the world's Key Biodiversity Areas (KBAs), less than a third have completely pristine night-time skies, about a half lie entirely under artificially bright skies and only about a fifth contain no area in which night-time skies are not polluted to the zenith. The extent of light pollution of KBAs varies by region, affecting the greatest proportion of KBAs in Europe and the Middle East. Statistical modelling revealed associations between light pollution within KBAs and associated levels of both gross domestic product and human population density. This suggests that these patterns will worsen with continued economic development and growth in the human population.
