摘 要:Climate conditions have long been acknowledged as a pivotal factor shaping regional productivity and influencing available resources,consequently playing an important role in driving social changes throughout human history[1–3].In ancient East Asia,the Chinese agrarian civilization emerged around 4000 years ago in northern China,the region termed the“Central Plains”.This region faced recurrent episodes of large-scale social unrest,profoundly impacting the societal structure and dynastic cycles[4].These episodes were marked by extended civil peasant uprisings and/or incursions from northern nomadic tribes,often spanning decades to centuries[5].Both the agrarian societies in the Central Plains and the husbandry-based nomadic tribes in the vast northern grasslands,characterized by semi-arid and semi-humid climates,were notably sensitive to climate variations[6].
