This type of research reflects the questions architects and urban designers typically ask, rather than those that preoccupy planners. For such research to be effective, the physical complexity variable must be controlled at the level at which real design decisions are made. “Space syntax” research attempts to do this by treating built environments as systems of space, analysing them “configurationally”, and trying to bring to light their underlying patterns and structures. Results from space syntax research into many aspects of urban space and how it works show a consistency which suggests that analysing spacial structure can be a general means of investigating the structure and function of cities. It may, in effect, be the common language of the city.展开更多

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
