Annotation:::: The paper focuses on issues of resources, environment, and development, and uses the method of documental study for a comprehensive review of recent research. After analysing literature related to eco-migration and mountain migration in China, the paper finds that eco-migration has increasingly drawn concern of the public since the late 1990s, and that relevant research deals with a wide range of topics from classification, meaning, necessity, and feasibility of eco-migration, to the problems, policy proposals, and evaluation of its benefits. The implementation of eco-migration projects in poor mountain areas produce two results: poverty reduction and alleviation of environmental deterioration. According to the authors, it is important to persist with the idea of development aimed at integrating a concentrated population with industrial development and urbanization related construction. Prior research from different angles suggests the need for ideas and guidance conducive to the practice and policy making for eco-migration projects to be implemented in all related areas, and also states the importance of laying a solid foundation for subsequent eco-migration-related research. The authors conclude that overall, research on eco-migration still remains at an initial stage.The paper is a project supported by the National Social Sciences Fund of China, numbered 06BJY028.
