摘要
Spatial-temporal scales effects are general among human-nature interactions.However,the laws and mechanisms of the interaction between humans and the environment at different spatial-temporal scales remain to be identified.The Hexi Corridor in Northwest China is located in the eastern section of the Silk Road and is one of the world’s first long-distance cultural exchange centers.Here we present a comprehensive dataset of the Hexi Corridor,including changes in environments,population,wars,famines,settlements,and ancient oases from the Neolithic to the historic period.Results show that humans adapt to climate change on the millennium scale by choosing corresponding production methods.Environmental change,civilization evolution,and dynasty replacement interrelate on the decadal and centennial scales.Social crises are closely linked to extreme weather events on the interannual scale.On the basis of these results,we find similar time scale effects in the world’s major ancient civilizations.We do so by analyzing their processes of civilization evolution.
