【摘要】 城市更新改造的难点在于如何做到可持续发展，即在如何保存城市历史信息的基础上完善城市基础设施，改善城市空间品质，因此，在城市更新进程中，建成区的城市空间如何得到延续与发展就成为一个重要的课题。本文的论述结构为： 第一章：提出研究课题。就我国当前城市发展的背景，并针对北京中关村地区的城市空间发展状况，说明本课题的研究意义、内容、目的，并对本课题的内容、范围、研究对象等等进行界定。 第二章：概述研究对象。对北京中关村地区城市空间的发展脉络进行简单梳理，重点就该地区的城市空间现状作一个整体概括，并将中关村地区与国内其他科研文教区以及国外的科学城进行一定的比较分析，总结出中关村城市空间的特点以及存在的问题。 第三-五章：案例分析研究。选取三个城市空间案例通过文献考据、实地调研、专家访谈的方法进行分析研究，总结出各类型城市空间的优缺点，并提出与之相适应的有成效的城市更新模式。这三个城市空间案例是：（1）中科院物理所大院。 以所在街区作为一个空间单元，从大院与周边城市空间的相互关系，大院内部的空间界定、尺度、组织系统等方面作了一定的分析研究。肯定了物理所大院的更新模式，即小规模局部改建，区域性环境整治所具有的促进城市空间持续性的积极意义。（2）四通桥。针对四通桥节点变通不畅，购物场所分散的问题，提出了适度规模合理改建的更新模式;（3）海淀图书城。从空间到界面，从设计到施工管理，乃至区域环境等方面，对步行街这一特殊城市空间作了比较深入的分析和研究，肯定了海淀图书城居于原海淀西大街的位置、尺度、环境所采取的小规模有机更新的模式。 第六章结语：概括总结本文的意义、目的和工作内容。 我们认为，中关村地区在发展方向上，应立足本地区既有的城市空间特点，采取因地制宜的城市更新模式持续完善建成区的硬件设施。优化空间环境，同时保留有意义的城市历史信息，使城市历史文化得到延续。更多还原

【Abstract】 The difficult point of the urban renewal lies in how to attain the sustainable development; i.e., how to perfect the urban infrastructure and improve the urban space qualities on the basis of the preserving the excellent urban historical information. Therefore, in the process of urban renewal, how to prolong and develop the urban space of districts has become an important subject. Here is the illustration structure of the thesis:In Chapter 1, the study subject is put forward. Based on the background of the current urban development in our country and according to the urban space development situation at Zhongguancun area, Beijing; the study meaning, content, purposes of this subject are explained. In addition, the content, scope and study objects of the subject are also defined.In Chapter 2, the study objects are briefly illustrated. The development vein of the urban space at Zhongguancun area in Beijing is briefly summarized. Emphasis is put on an overall summary on the current situation of the urban space of the area. An analysis and comparison of the area with other domestic areas of scientific researches, culture and education and the foreign science parks are made. The characteristics of the urban space of Zhongguancun and its existing problems are summarized.Case analysis and study are presented in Chapter 3, 4 and 5. Three cases of the urban space are selected. Through literature examination, site-investigation and interviews of specialists, analysis and studies are made, advantages and disadvantages of different kinds of urban space are summarized and the corresponding effective urban renewal patterns are put forward: (1) the compound of the Physics Institute of the Chinese Academy of Sciences. Taking the community where the compound is located as a space unit, definite analysis and studies have been made on the mutual relationships of the compound and its neighboring urban space, and the space definition, dimensions and structural system within the compound. The renewal pattern of the compound of the Physics Institute is approved, i.e. a small-scale partial reconstruction, Regional environmental enhancement plays a positive role in promoting urban spacesustainable development; (2) Stone Bridge. According to the traffic jam at the bridge and the scattering of shopping centers, a renewal pattern of a reasonable reconstruction on an appropriate scale is put forward; (3) Haidian Book Plaza. From space to edge, from design to construction management and the regional environment, rather deep analysis and investigation have been made on the pedestrian mall, a special urban space. The small-scale and organic renewal of the place, dimension and environment of the Haidian Book Plaza located originally at the West Street of Haidian, are all approved.Chapter 6 contains conclusions that summarize the meaning, purposes and working content of the thesis.We assume that for the development direction of Zhongguancun area, it is important that the development should be based on the regional existing urban space characteristics. In the urban renewal patterns, it is necessary to do what is appropriate in the light of local circumstances in the continuous improvement of the hardware facilities of districts already built up. In such a way, space environment could be improved, and at the same time meaningful urban historical information could be preserved, so that urban history and culture could be prolonged.更多还原
