基于空间句法的城市空间形态量化分析是一种通过建立数字模型进行空间分析的方法，这种方法可以客观描述各类型城市空间的发展状态和存在的问题，结合相关数据可进一步分析影响城市空间形态变化的深层次原因。运用空间句法理论中的轴线法构建张家口市线段网络模型，并通过GIS对张家口市14 394个POI兴趣点进行点密度分析，用于检验线段网络模型的合理性，在此基础上借助Depthmap软件平台对张家口市区空间的整合度、协同度和选择度进行量化分析。结果表明张家口城市空间形态具有以下特征：（1）部分片区周边空间过于复杂，步行体验有待提高；（2）主城区核心突出，有逐步形成南北双核心的趋势；（3）道路交通南松北紧，部分道路交通可达性较差；（4）城市边界形态逐渐向南北扩张，且南部新城扩张速度快于北部老城。

A line segment network model for Zhangjiakou was constructed by using the axis method in space syntax theory based on the data from city center area of Zhangjiakou in the paper. The point density of 14 394 points of interest(POI) in Zhangjiakou was analyzed through GIS to evaluate the rationality of the line segment network model. Based on the model the spatial integration, synergy and selectivity of Zhangjiakou urban space were quantitatively analyzed with the help of Depthmap software platform. The results showed that the urban spatial morphology of Zhangjiakou took the characteristics that(1) the surrounding space of some areas was too complicated and the walking experience needs to be improved; that(2) the core of the main urban area was prominent and there was a tendency to gradually form a north-south dual core; that(3) road traffic was light in the south and heavy in the north and the traffic accessibility in some roads was low; that(4) the urban boundary gradually expands to the north and south and the expansion rate of the new city in the south was faster than that of the old city in the north.
