空间句法是一种专业的空间关系分析方法。通过对空间进行尺度划分和分割，来研究空间与空间、空间与人的关系。主要运用轴线分析，凸空间分析，视域分析三种方法对空间的深度值、可达性、连接性等指标进行研究。目前学界针对空间句法开发的分析软件有：Depthmap软件系列、Confeego、空间设计网络分析(sDNA)和QGIS的Space Syntax Toolkit插件。 Space syntax is a specialized method for analyzing spatial relationships. By scaling and segmenting space, it studies the relationships between spaces and between spaces and people. The main methods used are axial analysis, convex space analysis, and viewshed analysis to study indicators such as depth value, accessibility, and connectivity of space. Currently, academic circles have developed analysis software for space syntax, including the Depthmap software series, Confeego, Spatial Design Network Analysis , and the Space Syntax Toolkit plugin for QGIS.
