The Intensive Utilization Of Urban Land During Rapid Urbanization

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...
