This paper also analyzes the relations between urban-rural construction land and urban-rural population transformation in the province,and expounds the possibility and necessity of carrying out human-land linking policy northern Anhui-Wanjiang. Based on the factors affecting human-land linking policy,this paper recommends that we should establish cross-regional trading policy system for land development rights in Anhui Province from four key links( urban entry,urban integration,rural exit,common urban-rural development),in order to effectively promote migrant workers' citizenization.展开更多
