标题： Artificial light at night: a global disruptor of the night-time environment

摘要： 光污染是由于人类活动导致夜间环境中光粒子浓度增加，从而改变了自然的黑暗水平。 光污染正在以深刻的方式改变地球上广大地区的夜间环境条件，并且是一个重要的压力源，其对生命的影响正被大量有说服力的研究所揭示。 在本文中，我们简要回顾了人工夜间光作为污染物的基本方面，描述了它的特性、规模和范围，其全球分布、时间与光谱变化趋势，以及其对当前光生产技术和普遍光使用方式的依赖性。 研究表明，光污染的整体影响不仅限于局部干扰，而是导致了夜间环境的全球性、多尺度的破坏。 显示英文摘要

摘要： Light pollution is the alteration of the natural levels of darkness by an increased concentration of light particles in the nighttime environment, resulting from human activity. Light pollution is changing in a deep way the environmental conditions of the night in wide areas of the planet, and is a relevant stressor whose effects on life are being unveiled by a compelling body of research. In this paper we briefly review the basic aspects of artificial light at night as a pollutant, describing its character, magnitude and extent, its worldwide distribution, its temporal and spectral change trends, as well as its dependence on current light production technologies and prevailing social uses of light. It is shown that the overall effects of light pollution are not restricted to local disturbances, but give rise to a global, multiscale disruption of the nighttime environment.
