What does it mean to immigrate from pastoral areas?

Ecological migration. Ecological migration in pastoral areas is "involuntary ecological migration" led by the government. Its main goal is to protect the special ecology of a certain area or restore the ecology of a certain area and reduce the poverty of herders. Ecological migration in pastoral areas is not a simple population flow, nor is it a problem of ecological environment and economic behavior. It includes the centralized process of the evolution of social organisms from traditional nomadic society to towns, and involves the issue of social and cultural inheritance.
