Quantification of Light Pollution Levels Based on Principal Component Analysis and Hierarchical Analysis Approach

Abstract

The level of light pollution risk is influenced by a number of factors. In this paper, we established a model to evaluate the risk level of light pollution in a certain area by considering various factors.Through the principal component analysis of the 12 indicators selected by us, three principal components are extracted, and then the analytic hierarchy process is used to evaluate the three principal components, so as to establish the corresponding weight of the three principal components, and finally establish the relevant evaluation function.
