【摘要】：随着长江三角洲经济发展带来的环境和成本问题,长江三角洲泛化势在必然。研究泛长三角地区的空间结构演变有利于正确认识和把握其空间发展规律,从而为泛长三角地区的发展提供科学依据。基于扩散理论并结合现代GIS空间分析技术,构建场扩散模型,从城市场空间结构演化角度分析泛长三角地区核心—边缘结构的形成过程。研究发现:泛长三角地区经历了行政中心孕育、行政中心极化、点轴扩散、网络化过渡和复合式核心—边缘结构形成五个阶段。城市场主体区经历了"之"字型—"几"字型—"虾"型—"鳊鱼"型四种空间形态;场强极强区—场强较强区—场强一般区面积呈递增格局并且各自逐年递增;城市节点、扩散通道(线)、行政区面的扩散值大大增强,但中部区域普遍大于外缘地带。
[Abstract]:With the environmental and cost problems brought about by the economic development of the Yangtze River Delta, the trend of the Yangtze River Delta generalization is inevitable. The study of the evolution of spatial structure in the pan-Yangtze River Delta region is conducive to the correct understanding and grasp of its spatial development law, thus providing a scientific basis for the development of the pan-Yangtze River Delta region. Based on the diffusion theory and modern GIS spatial analysis technology, the field diffusion model is constructed to analyze the formation process of the core edge structure in the pan-Yangtze River Delta region from the perspective of the evolution of the urban market spatial structure. It is found that the pan-Yangtze River Delta region has undergone five stages: administrative center gestation, administrative center polarization, point axis diffusion, network transition and the formation of composite core-edge structure. The main area of the city market has experienced four kinds of spatial forms: "zigzag"-"several"-"shrimp"-"bream"; the area of extremely strong field, strong field and general field strength is increasing and increasing year by year; The diffusion value of the diffusion channel (line) is greatly enhanced, but the central region is generally larger than the outer boundary zone.
