术语“往复性人口移动”的详细信息

英译术语:

oscillatory movement of population

汉语语境:

绝大多数农民离开农村，并不意味着彻底地脱离农村，他们的根还在农村，他们到城市只是“打工”，经过或长或短一段时间后，他们中许多人最终还要回到农村定居。他们到城市的目的，只是为了赚一笔钱，以便更好地过农村生活。当老的一批从城市回到农村，新的一批年轻人则离开农村进入城市，循环往复，形成了往复型的人口流动模式。

英语语境:

For most peasants, leaving the countryside does not mean being away forever. Instead, they will go back and still settle in the countryside after a certain period of time. After all, they have their roots in the countryside, and they just go to work in the city. The purpose of going to the city is to work and make a sum of money so that they can lead a better life in the countryside. When the elderly come back from the city, the young will succeed, hence the oscillatory movement of population.
