摘要 基于1990、2000、2010和2017年4个时期的Landsat遥感影像,运用分形理论和空间句法分析苏州城市外部和内部空间形态演变特征,并揭示其影响机理。结果显示:①从城市外部形态演变来看,苏州城市外部用地扩展经历"低强高速"、"中强中速"和"高强低速"3个发展阶段。②从苏州城市内部形态演变来看,全局集成核规模不断扩大且集成核形态逐渐完善,由树状单中心集成核向轮状多中心集成核转变。③苏州城市内外部形态演变具有一定规律性,基于道路交通系统和用地扩展的城市内外部空间形态演变呈同步性;外部和内部维度均凸显出城市形态呈"条带状多核"→"组团状行政型多核"→"组团状功能型多核"演变趋势。④自然因素、经济因素、交通因素和政策因素是导致苏州城市空间形态演变的主要驱动力。 Urban spatial form is the important basis of urban planning and construction. Taking Suzhou as the research object and based on Landsat remote sensing images in1990, 2000, 2010 and 2017, this paper analyzes the morphological evolution characteristics of urban exterior and interior space, and reveals its influence mechanism applying fractal theory and space syntax. Results display: 1) From the urban external morphological evolution, the expansion of urban external land has successively experienced three stages of development, namely,"low strength and high speed","medium strength and medium speed" and "high strength and low speed". 2) From the urban internal morphological evolution, the global integrated core scale is continuously expanding and the integrated core form is gradually improved. Integrated core transformation from a single center in the early 1990 s to a multicenter. 3) The evolution of urban internal and external forms has certain regularity and synchrony based on road traffic system and land expansion. The evolution trend of urban forms both in external and internal dimensions is "stripped multi-core","administrative cluster multicore" and functional cluster multicore. 4) Natural factors, economic factors, traffic factors and policy factors are the main driving forces for the evolution of Suzhou urban spatial form.
