| 摘 要： | 城市群是中国推进新型城镇化的主体形态,也是中国参与全球治理的基本单元,因而关于其范围界定研究一直是地理学关注的重要议题。突出地理学自然—人文要素融合研究优势,在改进传统万有引力模型、交通可达性、金融联系网络等定量分析方法基础上,结合主体功能区、语言—文化地理和国家战略等定性方法,集成构建城市群空间范围界定综合方法,据此在上海、江苏、浙江、安徽“一市三省”内遴选出26个城市,作为长江三角洲城市群的组成范围。尝试为城市群范围界定方法研究提供一种新思路,也希望能够为相关城市群规划编制工作提供依据和参考。

| Abstract: | Since China's reform and opening-up, with the increasingly rapid industrialization and urbanization process, urban agglomeration has become the main spatial component of the new-type urbanization. Urban agglomeration has also tended to be the most important agent of China to compete globally. Recently, China's central and local governments have paid special attention to the development of urban agglomeration through a series of regional plans and policies. For example, the "National New-type Urbanization Planning" has indicated that urban agglomeration should be the main form of new-type urbanization in transitional China. Many regional plans have been issued to promote the development of urban agglomeration, so as to reshape China's economic geography and regional strategies. Therefore, the definition and related research of the scope of urban agglomeration have been the subject of heated debates. Although the definition of the scope of urban agglomeration has been an important topic of scholarly attention, there are no generally accepted, efficient, and credible methodological system, as well as a set of techniques to identify urban agglomeration in the related literature. Based on the existing studies and geographical perspective, this paper highlights the advantages of the comprehensive analysis on natural-human factors. With regard to the methodologies, we aim to improve quantitative methods such as traditional gravitational models, traffic accessibility and financial connection networks, and we also combine some qualitative methods such as function oriented zoning, language-cultural geography and national strategy. In summary, this paper proposes an integrated method for defining the spatial scope of urban agglomeration. Taking the Yangtze River Delta, which includes Shanghai, Jiangsu, Zhejiang and Anhui, as an example, this paper conducts the qualitative analysis by using the methods such as function oriented zoning, language-cultural geographic relationship, and the requirements of national regional strategies. Furthermore, we also conduct the quantitative analysis by applying the methods such as economic gravity, traffic accessibility, and financial connection network. Then, we define the scope of the Yangtze River Delta urban agglomeration as a set of 26 cities, led by Shanghai, Nanjing, Hangzhou and Hefei. This paper will improve the effectiveness and precision for the scope definition of urban agglomeration by the combination of qualitative and quantitative analyses. And, this study will contribute to the innovations of related methodologies, which are useful for the planning of urban agglomeration especially the scientific definition of the scope of urban agglomeration scope. |
