Temporal Dynamics and Influencing Factors of Light Pollution in Guangzhou

Abstract

This paper examines the seasonal variations in light pollution levels in Guangzhou, China, and identifies the key factors driving these fluctuations. It highlights the impact of urban infrastructure, industrial activity, weather conditions, and socioeconomic factors on light pollution levels throughout the year. Seasonal changes in daylight duration, temperature, and rainfall patterns are explored in relation to their influence on the city’s light pollution. The paper also discusses the ecological and health implications of light pollution, focusing on the disruption it causes to wildlife and nocturnal species, as well as the associated risks to human health, including sleep disorders and chronic diseases. Technological solutions, such as the adoption of energy-efficient LED lighting, and regulatory efforts to mitigate light pollution are also considered. Finally, the study outlines potential strategies for managing light pollution in Guangzhou and other rapidly growing urban areas.
