在新西兰南岛有个仅有800多名居民的小镇,叫特卡波。从1965年开始,这里就对夜间的灯光实行管制:所有照明灯的顶部都要加一个盖子,各家各户的灯只能朝下而不能朝上照。这就是说,小镇的夜空必须保持黑暗,不能有光亮。 In the South Island of New Zealand there is a town of just over 800 inhabitants, called Tekapo. From 1965 onwards, there was regulation of the night lights: a cover was placed on the top of all the lights, and the lights of each household could only be directed downward and not upward. This means that the town’s night sky must remain dark and not bright.
