Meanwhile,London,as a world city with more than 200 years of industrialization and urbanization,has accumulated rich theoretical and practical experiences for land use planning in a major urban area,such as the creation of Garden Cities,a designated Green Belt and New Towns. This paper firstly analyzes the main characteristics of the spatial distribution of the built-up area,arable land and conservation land in Beijing. Then,some of the key aspects of urban fringe planning in the London region are examined. Lastly,several implications from the experience of London are provided with respect to land-use planning for Beijing,concentrating on a re-appraisal of land-use functions around Beijing,measures to improve the green belt,the development of small towns to house rural-urban migrants and urban overspill,and effective implementation of land-use planning.展开更多
