论文摘要
光污染是一个在全球范围内的问题,对人类健康和自然生态系统产生了一系列不利影响。利用人造夜空亮度的新世界地图集,Viirs录制的辐射和国内生产总值(GDP)数据,我们比较了光污染水平,以及在美国的州和县水平的人口大小和GDP的光通量以及欧洲地区2)和省级(nuts2)和欧洲的水平。我们发现欧洲最污染区域之间的差异为6800倍,人均光通量的差异为120倍,每GDP单元的通量差异为267倍。然而,我们发现美国县之间的差异更大:天空污染的差异为200,000倍,人均光通量的差异为16,000倍,每GDP单元的光通量差异为40,000倍。这些发现可能会为决策者提供信息,有助于减少与光污染相关的不利环境,文化和健康后果。
Light pollution is a worldwide problem that has a range of adverse effects on human health and natural ecosystems. Using data from the New World Atlas of Artificial Night Sky Brightness, VIIRS-recorded radiance and Gross Domestic Product (GDP) data, we compared light pollution levels, and the light flux to the population size and GDP at the State and County levels in the USA and at Regional (NUTS2) and Province (NUTS3) levels in Europe. We found 6800-fold differences between the most and least polluted regions in Europe, 120-fold differences in their light flux per capita, and 267-fold differences in flux per GDP unit. Yet, we found even greater differences between US counties: 200,000-fold differences in sky pollution, 16,000-fold differences in light flux per capita, and 40,000-fold differences in light flux per GDP unit. These findings may inform policy-makers, helping to reduce energy waste and adverse environmental, cultural and health consequences associated with light pollution.
