Agricultural Changes and Ethnic Migration in the Beipan River Basin of Yunnan-Guizhou Region from the Pre-Qin to Han and Jin Dynasties
From the pre-Qin to the Han and Jin Dynasties,the primitive agriculture of the Beipan River basin in the west-ern part of the Guizhou Plateau underwent major changes,and the process of agricultural change can be divided into three stages according to the changes in production tools,technology,and variety of food crops.The main reason for the change was that the two migrations of Dian and Han immigrants from the Warring States period to the East Jin,West Jin and Southern Dynasties brought advanced agricultural tools and technology,and the primitive agriculture in the Beipan River basin entered the stage of farming with hoes and ploughs,and the production mode of traditional agriculture appeared.However,advanced agricultural methods did not spread in the Beipan River basin,and the local area maintained a situation where multiple means of livelihood and agricultural production patterns coexisted.
