摘　　要：以内蒙古自治区东部地区区域性中心城市赤峰市为研究区,利用空间句法理论中的轴线分割法,借助GIS技术平台和Depthmap软件,提取1964年社会主义建设时期、1984年改革开放初期及1996年、2003年、2009年、2018年快速城市化时期六个时间段的城市交通网络轴线数据,通过空间句法的集成度、集成核和协同度等参数值对赤峰市城市内部空间形态特征进行定量化分析。结果表明赤峰城市内部空间形态演变具有以下特征:近六十年来,赤峰市以老城区为中心主要向北、向西扩展;全局集成核由树枝状逐渐向网格状转变,城市整体结构趋于规整;扩展模式由单核心扩展向多核心扩展转变,呈现多核心组团状扩展模式,各组团以独立发展为主且连通性较差;协同度整体上呈下降趋势,城市局部空间与全局空间的互动性减弱,从局部到整体的空间感知能力降低。GIS was used as the technology platform combined with Depthmap software to study the spatial morphological characteristics of Chifeng city,a regional central city in the eastern part of Inner Mongolia Autonomous Region since 1964,based on the axis segmentation method in space syntax theory in this paper.The axis data of the urban transportation network in 6 typical periods of Chifeng city were extracted to quantitatively analyze the spatial morphological characteristics through the global integration values and local integration values and discuss the relationship between the road network pattern and urban morphology.The results showed that the evolution of the urban internal spatial pattern of Chifeng City had the following characteristics:Chifeng took the old city as the center and expanded mainly northward and westward in the past sixty years;the global integrator gradually changed from dendritic to grid like,suggesting that the overall urban structure tended to be normalized;the expansion mode had changed from single-core to multi-core,each core developed independently and had low connectivity;spatial synergy degree was on the decline,the interaction between the local space and the global space of the city weakened,spatial perception ability from part to the whole reduced.
