摘　　要：利用空间句法和GIS理论,以整合度作为可达性评价指标,顾及地铁网络与基础路网之间的关系,引入“可达性吻合度”概念,对城市公共交通系统可达性进行研究.为检验方法的有效性,以成都市地铁网络和道路网络为例进行公共交通可达性实验分析.结果表明:利用GIS和空间句法模型可以合理评价城市公共交通网络的可达性;成都市公共交通系统与城市区域发达程度相契合,可达性随区域发达程度变化而变化.Using spatial syntax and GIS theory,taking integration degree as accessibility evaluation index and considering the rela⁃tionship between subway network and basic road network,the concept of“goodness of fit for accessibility”was introduced to study the accessibility of urban public transportation system.In order to test the effectiveness of the method,the accessibility of public transportation was analyzed by taking Chengdu metro network and road network as an example.The results show that the accessibility of urban public transport network can be reasonably evaluated by using GIS and spatial syntax model.The develop⁃ment of public transportation in Chengdu is consistent with the development of urban region,and its accessibility changes with the regional development degree.
