The Research On The Principal Function Area In The Major Coastal Cities Of Yangtze River Delta

It is an important act to push the formation of principal function area, which was brought forward by government in the 11th "Five-Year Plan". And It is not only an important premise to carry out scientific development, change the mode of economic growth and promote harmony between human being and the nature, but also a major innovation to manage the land and space development idea and strategies for our country. The principal area design could enrich and deepen coordinated regional development strategy.In this paper, based on the existing and mature practices and theories form domestic and abroad, we chose the county as the regionalization unit, and analyzed the natural environment, the economic growth, the social development and the challenge in the main coastal cities of Yangtze River Delta. The capacity of nature environment and resource, the density of current development and the potential of future development were calculated. On the basis of above analysis, the index system for principal function area was constructed, and index's weights were fixed with the method of Analytic Hierarchy Process (AHP). Finally, the capacity of the various regions were calculated with the method of the State Spatial Method, Moreover, Based on the quantitative analysis and qualitative analysis, a distribution map of the principal function area in the main coastal cities of Yangtze River Delta was formed. At the same time, according to the requirements of constructing principal function area, we put forward some relevant policy recommendations.Based on the research task, this paper is divided into a total of seven chapters:Chapter 1: Introduction. This chapter includes the research background, the research status, the research significance, the research ideas and the paper's framework. Chapter 2:Theoretical analysis. This chapter includes the related concepts and the theoretical basis of the main function area. Chapter 3:Build index system. This chapter includes the natural environment, the economic growth, the social development and the analysis of space layout in the main coastal cities of Yangtze River Delta, and determines the type of the space evaluation, and sets up the contents of the index system. Chapter 4:The methods of the main function area. This chapter includes the analytic hierarchy process, the state spatial method;the 3D cube. Chapter 5:The development planning of the main function area. This chapter includes obtaining weights by AHP, and getting the capacity of the various regions by the state spatial method, and forming a layout for the main function area in the main coastal cities of Yangtze River Delta by the 3D cube. Chapter 6:District assessments and suggestions. This chapter includes the relative measures from the point of optimized, prioritized, limited development and banned exploitation area. Chapter 7:Conclusions and weaknesses. This chapter includes the main conclusions of the paper and the weaknesses of the research.
