| 英文摘要 | The global COVID-19 outbreak severely hampered the growth of the global economy, prompting the implementation of the strictest prevention policies in China. Establishing a significant relationship between changes in nighttime light and COVID-19 lockdowns from a geospatial perspective is essential. In light of nighttime light remote sensing, we evaluated the spatiotemporal dynamic effects of COVID-19 city lockdowns on human activity intensity in the Zhengzhou region. Prior to the COVID-19 outbreak, nighttime light in the Zhengzhou region maintained a significant growth trend, even under regular control measures. However, following the October 2022 COVID-19 lockdown, nighttime light experienced a substantial decrease. In the central area of Zhengzhou, nighttime light decreased by at least 18% compared to pre-lockdown levels, while in the sub-center, the decrease was around 14%. The areas where nighttime light decreased the most in the central region were primarily within a 15 km radius, while in the sub-center, the decrease was concentrated within a 5 km radius. These changes in both statistical data and nighttime light underscored the significant impact of the COVID-19 lockdown on economic activities in the Zhengzhou region. China implemented some of the strictest COVID-19 control measures globally, yet research on large-scale city lockdowns in China remains limited. Zhengzhou, being one of China's major cities with stringent control measures and a global hub for electronic goods processing and production, has seen significant impacts on the global electronic goods supply chain due to these measures. Our research offers a new approach to assessing the impact of pandemic transmission in urban systems, providing valuable insights from a geographic spatial perspective. The utilization of nighttime light data highlights how computer-based data analysis enhances our understanding of the spatial scope and dynamics of large-scale pandemics in urban areas. Nighttime light in the central area of Zhengzhou decreased by at least 18% The reduction in nighttime light was observed within a 15-km radius of the central area Lockdown measures significantly impacted economic activities in Zhengzhou |
