| 摘 要： | 城市形态演化反演城市土地利用模式的转变,是内部最低成本土地利用模式驱动力的外部表达。这一城市空间格局演变遵循本文提出的"外部扩张,内部填充"相互交替总体规律。它既是集聚与扩散驱动因子作用的结果,也是植入与再植入的"扬弃"选择过程的交互作用产物。基于最低成本—周期扩张模型的假设,本文选取昆明建成区近现代的影像资料,运用形态学的视角分析城市空间结构的变迁,探寻城市形态演化规律。结果表明:(1)从城市形态演变的一般理性微观、宏观过程来看,城市形态变迁在统计学上遵循最低成本—周期扩张规律假设;(2)在最低成本—周期扩张模型内,公共投资与基层设施建设变动及其要素替代效应对形态的周期性扰动响应是其核心作用机制。

| Abstract: | The evolution of urban morphology is the changing pattern of urban land use.It is the external morphological outcome of the internal impetus of minimum cost on urban land use model.This paper argues that the process of morphology evolution is the result of alternant pattern of external expansion and internal infilling of land use in urban areas,which is the aufheben conducted by the interweaving behavior between concentration and dissimilation,as well as by the process of embedment and re-embedment of socio-economic action. Based on the above hypothesis,we select the(remote sensing) images of Kunming in temporal serial from 1909 to 2006,using morphological perspective to analyze the changes of urban spatial pattern and explore the evolution of urban morphology.The results are revealed that:(1) from the view of the rational micro-process and macro-process,in general,the evolution of urban morphology follows the pattern of the minimum cost-cyclic expansion in the statistics;(2) based on the minimum cost-cyclic expansion model,the core mechanism that drives the morphology of periodic changes is based on the impact between alternant pro-growth infrastructure investment and pro-consumption public investment infrastructure changes,as well as factor substitution effects in each spatial phase. |
