A better way to measure light pollution level

"Leading the era of science and technology, advancing with The Times." However, the ever-increasing artificial light sources, while meeting the needs of lighting and decoration, are also causing new sources of environmental pollution because they are being used excessively or improperly. The increasing use of artificial light sources has created a new source of environmental pollution, namely light pollution . We aim to make people more aware of the effects of light pollution and to help solve the problem of measuring the effects of light pollution . We studied the light pollution of glare pollution, light intrusion pollution and light spill pollution , used regression analysis and cluster analysis to build the evaluation model of these three types of light pollution, and established the evaluation index of seven levels of light pollution based on the average distance between groups and the definition of light pollution degree. The evaluation index can be widely used in light pollution assessment in various places, and its evaluation results are of some significance for people to further understand the severity of light pollution nowadays and help the government to monitor and intervene.
