摘　　要：街道在城市生活中扮演着极为重要的角色,它不仅是交通的主要载体,也是重要的城市开放空间。在龙瀛和沈尧提出的街道城市主义思想的基础上,对成都全市街道活力展开定量探索,明确了"街道""活力"和"街道城市主义"的概念,构建了街道活力定量评价的指标体系,分别探索了A类(公共管理与公共服务)、B类(商业服务业设施)和R类(居住)街道活力的外在表征和街道活力构成因素的关系。研究表明,不同类型街道的活力影响因子差异较大:A类街道活力受天府广场距离制约明显,B类街道活力则与地铁口紧密关联,R类街道活力更多受功能混合度影响。Streets as traffic carrier and public space of a city are playing increasingly important role in daily city life.We quantitatively explore the street vibrancy of Chengdu,while referring to street urbanism proposed by Long Ying and Shen Yao in 2015.We firstly define the concepts of street,vibrancy and street urbanism,followed by developing the factors for quantitatively evaluating street vibrancy at the street level.These factors range from function density,function diversity,accessibility to metro stations,distance to city center and subcenters,to street level and width.Linear regression has been adopted for identifying the impact of each factor on the street vibrancy,which is measured by population density derived from mobile phone traces.We specifically analyze the impact factors for public administration and service streets（Type A）,commercial streets（Type B） and residential streets（Type C）.
