Research on the Evaluation System of Light Pollution Risk Index

Abstract

Light pollution is the general term for the sum of various harmful effects of artificial light. This report aims to establish a light pollution risk level evaluation model through light pollution risk assessment, and provide effective intervention strategies to mitigate the adverse effects of light pollution. First of all, the report follows the principle of scientific and comprehensive, and establishes a comprehensive evaluation system for the risk level of light pollution. Then, the corresponding data were collected, 19 indicators such as average night illumination, electricity consumption, glare index, artificial light intensity were selected as evaluation indicators, and the entropy weight method-TOPSIS comprehensive evaluation model was constructed to quantify the data, and the weights of each index were determined, and it was found that the proportion of glare index and community lighting weight was the largest. Then, applied to four different types of sites, the level of light pollution risk in different regions was discussed. Finally, the stability of the data is verified and it is concluded that prosperous cities have the highest light pollution levels, while protected areas have lower light pollution levels. The model passed the stability test, and a variety of visualization methods were used in the article to make the results more intuitive.
