【摘要】 近年来，随着我国经济的迅速发展和城市化进程的加快，城市建设规模不断扩大，城市用地不断扩展。城市的合理扩展能够促进社会的繁荣进步，但只注重外延而不寻求内涵的发展，不仅浪费宝贵的土地资源，还将引起诸如生态环境破坏、污染加剧等方面的问题，威胁到整个社会的和谐与可持续发展。城市形态作为城市这一特殊巨系统的重要组成部分，对其开展定量分析和研究是城市地理学与城市规划领域的重要研究方向之一，具有一定的理论价值和现实意义。因此，本文在理论研究的基础上，以原杭州市区为例，对城市扩展形态及其驱动力机制进行了分析，研究的主要内容和结论包括以下四个方面： (1)对国内外城市形态扩展的相关研究进行了回顾和总结，着重对城市扩展模式、扩展驱动力机制以及城市扩展的合理规模作了比较和分析。 (2)在理论研究的基础上，以原杭州市区为研究区域，运用GIS技术，通过三项空间形态指标对城市形态的扩展进行了定量分析，得出了分形维数、形状指数上升，紧凑度指数下降的结论。由此说明：杭州市区的用地扩展类型为外延发展类型，城市内部填充不够。基于此，本文对杭州未来的城市发展提出了两点建议。 (3)深入探讨杭州城市用地扩展的驱动力机制，重点分析建成区面积与13项社会经济指标之间的相关性关系。 (4)在城市用地扩展的驱动力研究的基础上，选取七项指标，运用AHP法和格网赋分法，预测杭州2005年城市用地的扩展情况。预测结果与2005年实际情况较为符合，表明此方法可靠性良好，可用同样方法预测2010年杭州城市用地的扩展情况。更多还原

【Abstract】 In recent years, with the quickening pace of economic growth and urbanization, the scale of urban construction has been substantially enlarged with the built-up areas being expanded. A rational urban expansion can contribute to the social prosperity, while an irrational one will give rise to a lot of social problems, such as pollution, the loss of arable land and the deterioration of ecological environment. They will all pose a threat to the sustainable growth of our society. Consequently, it is of great significance to conduct a quantified research on the urban expansion morphology. This paper, on the basis of literature review, made a quantified and forecast research on the urban expansion morphology. Its contents and results were as follows:(1) This paper made a comprehensive review concerning urban expansion, focusing mainly on its type, driving force and its rational scale.(2) Based on the literature review, this paper explored the former Hangzhou city’s expansion through three spatial indicators and came to a conclusion that it belonged to an extension type. Thus, this paper put forward two relevant suggestions.(3) A thorough discussion was carried out into the driving force mechanism of Hangzhou urban expansion and a relation analysis was conducted involving built-up area and thirteen social and economic indicators.(4) On the basis of the driving force analysis, seven indicators were selected out to forecast the urban expansion situation of Hangzhou in 2005 through giving value to the grids and AHP method. The forecast results conformed to the reality well and a similar forecast can be conducted in 2010.更多还原
