摘　　要：2021年11月受各种因素影响,政府在庄河范围内实施了严格的限制措施。经过分析显示,在庄河实施限制后,2021年11月地表温度相较于2020年11月平均气温上升了10.37℃。该限令导致的人类活动减少,促成了中国2021年冬天来的更晚一些。这项研究表明,人类活动的短期变化可以在区域范围内产生相对迅速的生态影响。In November 2021,due to various factors,the government implemented strict restrictions within the zhuanghe River,including blockades,traffic restrictions,social distancing and movement restrictions.These limitations provide testing grounds for exploring the effects of human activities on vegetation cover and surface temperature.So using remote sensing big data,we investigated how closures and traffic restrictions affected autumn vegetation in China in 2020.Our analysis shows that the November 2021 land surface temperature was 10.37°C warmer than the November 2020 average after the zhuanghe restrictions were implemented.The reduction in human activity caused by the ban contributed to a later winter in 2021.This study shows that short-term changes in human activity can have relatively rapid ecological impacts on a regional scale.
