Abstract

Due to the sampling and difficult quantification of light itself, people often cannot have an accurate understanding and evaluation of light pollution. Therefore, based on the current situation and harm of modern light pollution, this paper analyzes the factors causing light pollution from multiple perspectives, applies the multiple linear evaluation method and uses the least square method to estimate the parameters, and further uses the entropy weight method to determine the weight of relevant parameters, so as to construct a kind of light pollution risk level evaluation model. Four regions with different development levels were selected for numerical simulation to verify the correctness of the theoretical analysis of the model. The calculation of light pollution indicators through the model can help people more comprehensively understand and evaluate the light pollution level of a region or city.
