As the harm of light pollution to human life and ecological systems becomes increasingly severe, the control of light pollution has attracted more and more attention. To accurately measure the risk level of light pollution, an evaluation model was established. Firstly, four indicators that affect the degree of light pollution were identified, and a topsis model based on entropy weight method was used to calculate the scores of 9 cities for ranking and comparison with the actual rankings. The final result showed that the two rankings were close, indicating that the evaluation model is reasonable and the weights of the four indicators are as follows: electricity consumption: 0.2982, vegetation coverage rate: 0.1903, population: 0.3150, gross domestic product: 0.1964.
