先秦至汉晋时期云贵地区北盘江流域的农业变迁与族群迁徙

Agricultural Changes and Ethnic Migration in the Beipan River Basin of Yunnan-Guizhou Region from the Pre-Qin to Han and Jin Dynasties

先秦至汉晋时期贵州高原西部的北盘江流域的原始农业发生重大变迁,根据生产工具、技术、粮食作物品种等方面的变化,农业变迁过程可以分为新石器时代中期至商周、战国至西汉、东汉至两晋南朝时期三个阶段。造成变迁的主要原因是战国至两晋南朝时期滇人和汉人移民的两次迁徙带来先进的农具和技术,北盘江流域的原始农业进入锄耕阶段,而且出现了传统农业的生产模式。但是,先进农业方式没有在北盘江流域普及,当地维持了多元生计方式和农业生产模式并存的局面。

From the pre-Qin to the Han and Jin Dynasties,the primitive agriculture of the Beipan River basin in the western 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.
