摘要:

随着长江三角洲经济发展及其面临问题,长三角泛化已成为必然,研究泛长三角空间结构演变有利于正确认识和把握其空间发展态势,从而为泛长三角区域一体化进程提供问题依据。以场强模型为基石,根据扩散理论,构建了场对数扩散效应模型,从城市场这一新视角分析了泛长三角区域空间演进过程。泛长三角城市影响区自改革开放以来经历了疏点-“之”-“几”-“皮皮虾”-“鳊鱼”5种空间形态;根据这一空间形态极其演变规律提炼出疏点类型、散块类型、条带类型、团块类型、板块类型五种空间结构类型;在此基础上,由“以点建轴,以轴布面”思想,以产业结构整体升级为引导,对泛长三角区域进行空间整合,形成由三级中心城市、三级发展轴线以及内核城市群、邻接城市群和外缘城市群组成的核心-边缘结构三级产业城市群。

Abstract:

The generalization of the Pan Yangtze River Delta has become inevitable because of economy development and problems facing in the Yangtze River Delta. Researching evolution of economy space structure the Pan Yangtze River Delta can help us appreciate and grasp its trends of space evolution, and to provide the basic data for regional integration of the Pan Yangtze River Delta. The author analyzed evolution process of the Pan Yangtze River Delta depending on Diffusion Theory and constructing Diffusion Effect Model of Field Logarithmic. The research showed that the primary urban effective regions are distributed along the Yangtze River Delta and Hangzhou Bay. They evolve from shapes of sparse pots, “S”, pipi shrimp, to that of bream. Areas of extremely strong field regions, stronger field regions and ordinary field regions were found to decrease, while areas of weaker field regions and the weakest field regions were found to increase. According to evolution laws and mechanism of spatial structure of economy, accessibility, urban field in the Pan Yangtze River Delta, especially spatial structure urban field, on the principle of establishing development axis in accordance with city nodes, establishing planes in accordance with axis, we conducted spatial integration for city nodes, industrial development axis and industrial development metropolitan in the Pan Yangtze River Delta and built first grade industrial development axis as a hairbrush compositing of the development axis along the Yangtze River, coastal zone, huninghe, huhangqu. Under first grade industrial development axis of hairbrush, we set Nanjing, Hangzhou, Hefei, Suzhou, Ningbo as diffusion sources and built the second grade development axis. And field strength in the Pan Yangtze River Delta was classed as core area, adjoining area, outer area and based on it urban economic region in the Pan Yangtze River Delta was classed as kernel metropolitan, adjoining metropolitan, outer metropolitan.
