Evaluation Model Based On Optimized EWM Identifying Light Pollution

Abstract

Light pollution has negative impacts on wildlife, human health and the environment, disturbing the natural darkness of the night sky. However, there lacks an objective and feasible method measuring the risk level of light pollution. Therefore, we establish a mathematical evaluation model based on the integration of optimized EWM and TOPSIS to measure the light pollution of representative locations. According to the results, we conclude that the risk level of light pollution is positively correlated to the prosperity of commerce.
