摘要: 街道是城市中重要的公共活动空间。在街道城市主义的影响下，以武汉市街道空间为研究对象，展开对街道活力的量化研究。通过分析武汉市兴趣点数据的分布模式、密度等空间规律，将城市街道功能划分为生活型街道、商业型街道和景观休闲型街道，同时对应街道的自身条件、周边开发情况、街道功能等要素展开回归分析，发现街道功能密度、功能混合度和街道周边开发强度因素显著影响街道活力的形成，街道空间的自身要素如路网密度、街道宽度等也对街道空间活力有一定影响。
Abstract: Streets are important public spaces in the city. With the influences of street urbanism, we select Wuhan as a research object and expand quantitative research on street activities. This paper analyzes the density and the distribution pattern of Wuhan POI to categorize the city streets into living streets, commercial streets, and landscaped streets. The paper also conducts a regression analysis between urban streets and other street elements respectively. It is found that function density, function mixing degree, and development intensity around the street significantly affect the formation of street vitality, and the factors of street spaces themselves, such as network density and street width, also affect their vitality.
