摘　　要：空间拓扑关系是空间句法研究的基础.讨论了空间句法的系列变量,并以武汉市为例,提取武汉市的交通网络轴线地图,在GIS环境下讨论了不同尺度空间范围内的空间句法变量,得出空间可达性是评价城市空间形态的重要因子,而集成度是描述空间可达性的直接变量.利用空间句法变量可以进一步研究城市空间形态与人类活动的相互影响和相互关系.　The spatial topologic relation is the foundation of spatial syntactic research. A series of spatial syntactic variables is discussed in the paper. Taking Wuhan's traffic axial map as a case, spatial syntactic variables of multi-scale spatial extent based on GIS are analyzed. A conclusion is that the accessibility is the key factor that weighs an urban spatial morphology, and the integration degree is a direct variable describing accessibility. The interrelationship between the urban spatial morphology and the human activity can be studied more intensively by means of syntactic variables.
