Light Pollution, TOPSIS Model, Entropy Weight Method.Abstract
Light is an indispensable lighting source in human life. From the initial fire light source to the later electric light, light provides human beings with the ability to see things in the dark, which greatly expands the time and scope of human activities. However, in recent years, light pollution has become a major problem for people. To quantify and evaluate the impact of light pollution, In order to solve this problem, this paper establishes a TOPSIS model based on entropy weight, and uses Arc GIS software to quantitatively analyze the visual light pollution map. Seven evaluation indexes are selected and quantified. Then, the weights of seven evaluation indexes are obtained by using the TOPSIS model based on entropy weight, and the light pollution evaluation of the selected cities is carried out. Finally, the comprehensive ranking of the light pollution degree of the five cities is obtained.Through this research, it is of great significance to protect human health, maintain ecological balance, promote astronomical observation and improve urban planning and lighting design.
