Land, nature, and the social environment in contiguous poor regions are harsh and difficult to change. The poor adaptive capacities of the socio-ecological systems of these regions are the main causes of deep, persistent poverty. In February 2016, the Chinese government issued a policy proposing to promote poverty alleviation by relocation (PAR) by means of the "Linking increases in urban construction land with decreases in rural construction land" policy (or simply, the "Link Policy" or LP), which intends to realize the sustainable social and economic development of local villages. Since then, many pilot projects have been carried out across the country based on local resources, environment, and economic development; however, few related studies on these cases have been conducted. After a review of poverty alleviation policies, this paper first introduces the unsustainable conditions of poor rural areas and the implications and advantages of PAR under the Link Policy; we then analyzed the complete PAR process, including formulation, implementation, and completion, by taking Tongyu County in Jilin Province as an example. The study found that the "whole village relocation" model practiced in Tongyu County was relatively successful in terms of improving the living environment, income, and public services of local villagers. On the other hand, there were three main problems: first, many follow-up industries were dominated by the village collectives and heavily dependent on government support or subsidies; second, the newly built village faced the dilemma of "re-hollowing" due to the out-migration of young people and the aging population; third, it was difficult to achieve a true requisition-compensation balance of farmland.
