N2 - Artificial light sources have a profound impact on the night sky, leading to reduced visibility of stars and contributing to light pollution. The environmental, physiological, and psychological consequences of light pollution are severe, including disrupting ecosystems, biological clocks, and endocrine imbalances in humans. Moreover, excessive lighting also wastes energy and exacerbates the energy crisis. This paper collects eight light pollution indicators and proposes a general measurement model for light pollution risk level using an improved PCA clustering algorithm. This paper also proposes intervention strategy optimization model to reduce the risk level, and evaluates the effectiveness of these interventions in Shanghai. Overall, this paper provides insights into the causes and consequences of light pollution, and practical solutions for mitigating its harmful effects.
