China and Chinese Academy of Sciences published many papers on this topic, but, research quality and influence need enhancing. In the past three years, their research work is more active; USA, German and UK are located in more important places in the international scientific collaboration networks. China has a weak collaborative relationship with other countries and institution; Research priorities from the auto-correlation Map of keywords include ecological conversation, poverty alleviation, area of origin and resettlement, migration sociology issues and relavant policies.
