Climate history decoded through ancient bamboo distribution in Yellow River Valley.
The distribution of bamboo in the Yellow River valley during the Qin and Han Dynasties can tell us about the climate history of that time. The change in bamboo distribution was not due to economic cultivation, but rather a sign of climate change. The presence of bamboo suggests a mild climate during the Qin and Han Dynasties, as shown in Zhukezhen's study on climate changes over the past 5,000 years.
