【摘要】 改革开放以来，我国的城市化得到迅速发展。然而，由于城市化进程与土地资源的利用过程紧密联系，城市化发展特别是加速时期的城市化发展，对土地利用的扰动极为剧烈。在我国，这种扰动主要表现为城市用地总量失控、结构失衡和生态恶化。我国土地资源十分有限，城市化发展不可能以无休止地侵占农用地为代价。“一要吃饭，二要建设”，提高土地使用效率，挖掘城市用地潜力，促进城市土地集约利用必将成为我国城市化的主要发展道路。从这个意义上来说，城市化进程中的城市土地集约利用研究显得特别重要。 全文共分为5个章节：第一章为绪论，介绍了本文的研究背景及意义，并对国内外的城市土地集约利用研究的进展作了综述，最后阐明了本文的研究思路和方法；第二章着重探讨和归纳了城市土地集约利用的基本概念，分析了推动城市土地集约利用的外部动力和内部动力，并从理论上演绎了城市化与城市土地集约利用之间的关系；第三章分析了南京市的城市化发展水平和城市土地集约利用现状，并在此基础上运用定量方法验证了城市化与城市土地集约利用之间的关系；第四章运用数量模型对南京市的城市土地集约利用潜力进行了宏观层次上的评价；第五章针对南京市城市土地利用现状提出了土地集约利用的政策建议。 研究得出的结论是：①影响城市土地集约利用的因素复杂多样，包括城市人口增长、经济发展、产业结构调整、技术进步、国家或区域宏观经济制度的变动和城市规划的制定与实施等；②在城市化发展的不同阶段，城市土地集约利用与城市化的关系不尽相同；在向心式城市化阶段(城市化初期和加速期)，城市化能够促进城市土地集约利用；③与国内同类城市相比，南京市的城市土地集约利用水平较低；④通过提高土地产出效益从而提高南京市的城市土地集约利用水平的潜力空间巨大，今后在挖掘城市土地集约利用潜力时，应把提高城市用地效益放在首要位置，同时加强城市土地投入和利用强度；⑤南京市城市土地集约利用的主要途径是优化城市用地结构及布局、旧城改造和充分利用地下空间，国土部门应积极发挥引导作用，充分运用政府和市场两种力量进行挖潜，同时应注意生态环境的保护。更多还原

【Abstract】 Since the adoption of the open and reform policy, the process of China’s urbanization has been accelerated. However, the urban land utilization has been greatly influenced by the rapid urbanization due to the tight relationship between urbanization and land utilization. The effects of the rapid urbanization resulted in the out-of-control of land supply, imbalance of land structure and deterioration of ecosystems in China. Land resource is important and limited in China; it is not feasible to occupy agricultural land without control for the urbanization. Two aspects of food supply and urbanization are both important but controdictionary in land utilization. Therefore, it is vital to improve the land utilization efficiency during the rapid urbanization. The intensive urban land utilization might be an effective way to avoid the conflict of land for agricultural and urbanization utilization. Thus, the understanding of intensive land utilization is critical for the policy maker in the decision of the rapid urbanization of China.There are five chapters involved in this thesis. The first chapter is an introduction to discuss the background and significance of this research. The results related to this topic were reviewed and the study framework was proposed in this chapter. In the second chapter, the conception of intensive utilization of urban land was introduced and a systematic analysis of the driving forces in the intensive utilization of urban land was conducted. In the next chapter, the current situation of the urbanization and the intensive utilization of urban land in Nanjing city were analyzed and their relationship was validated by a quantitative method. In the forth chapter, the potential of the urban land intensive utilization in Nanjing city was assessed in macroscopical using a quantitative evaluation model. And in the last chapter, some policy suggestions were proposed to improve the intensive utilization of urban land in Nanjing city in the future.The conclusions of this research were drawn mainly as follows: ①The intensive utilization of urban land is influenced by many factors, including the growth of population, the development of economy, the adjustment of industrial structure, the progress of science and technology, the alteration of macroscopical policies as well as the establishment and actualization of urban planning; ②The relationship between intensive utilization of urban land and urbanization differs from various stages of urbanization. In the primary and accelerating periods, urbanization can improve the intensive utilization of urban land; ③Compared with similar cities in China, the level of intensive utilization of urban land in Nanjing city is low; ④The utilization efficiency of urban land should be improved firstly to increase the level of the intensive urbanization of urban land in Nanjing city, and the intensity of exploitation and investment is to be enhanced; ⑤The main approaches to the更多还原
