摘　　要：城市活力是城市高质量发展的关键表征。第三空间作为除了工作与家庭以外的另一种空间形式,是增强城市活力的重要载体。良好的街道可达性、充足的功能混合度及适宜的建设强度与建筑形态等是产生城市活力的空间基础。但是,现行城市设计中的第三空间布局往往是基于感性“设计思维”,缺乏对城市活力相关要素的理性分析。本文以武汉为例,探讨第三空间活力与哪些空间要素相关及如何相关等问题,进而构建以活力为导向的第三空间城市设计模式。研究过程:首先,建立与第三空间活力相关的要素库;其次,以武汉现状最具活力的地区为样本,利用多源数据量化要素库及第三空间活力,运用多元线性回归法构建数学模型,研究提出第三空间布局的普适性建议,并归纳第三空间布局的量化方法,以期在城市设计实践中进行应用。Urban vitality is a key index for high-quality development.The third place,as another form of spaces besides workplaces and homes,plays an important role in improving the urban vitality.High accessibility,high degrees of mixed land use,and desirable building forms and densities all form the spatial basis for urban vitality.However,the current layout of the third places is usually based on perceptual"urban design thoughts",which lacks the rational analysis on elements related to urban vitality.Taking Wuhan as an example,this paper explores which spatial elements are related to the third places vitality and how to relate them,and then constructs a vitality-oriented third space urban design model.The research process is as follows:firstly,a database of elements related to the third space vitality is established;secondly,the most dynamic areas in Wuhan are used as samples to quantify the database of elements and the third space vitality using multi-source data,and a mathematical model is constructed using multiple linear regression method to study and propose universal recommendations for the layout of the third space and summarize the quantification methods of the third place layout with a view to applying them in the urban design practice.
