Central Plains Climate in Shang and Zhou Dynasties

Central Plains Climate in Shang and Zhou Dynasties

Shang junior high school belongs to Yangshao warm period, and the climate is warmer than it is now. In his research, Mr. Zhu Kezhen said, "In the first two thousand years of nearly five thousand years, that is, from Yangshao culture to Anyang Yin Ruins, the average annual temperature was about two degrees higher than it is now, and the temperature in January was about three to five degrees higher than it is now."

The late Shang Dynasty, from 1 100 BC to 850 BC, was the first cold period after the Yangshao warm period. It is recorded in the literature that "tigers, leopards and rhinos were driven away", indicating that the climate became cold and heat-loving animals such as tigers, leopards and rhinos began to migrate. In addition, when the king of Wu attacked, it was "cloudy and cold in October, with rain and snow as deep as more than ten feet", from which we can also see that the climate was getting colder.

In the late Shang Dynasty, due to the exploitation of nature by human beings, although the production level has been improved, the ecological environment has also been greatly damaged, and the vegetation coverage rate is low, resulting in sandstorms in some parts of the north; That is to say, sandstorms have a great relationship with climate drought and cooling.
