Abstract Enhancing the vitality of urban public space is an important way to promote the high-quality development of cities and the construction of high-quality living space. This paper integrates the physical and virtual attributes of urban public space, proposes a framework for analysing the vitality of urban public space and an evaluation index system of "obvious and hidden mutual reference", and evaluates the vitality of parks and green spaces in Xi'an based on multi-source big data as an example, revealing the type of synergy between explicit and implicit vitality as well as the mechanism of revealing hidden vitality, thus proposing strategies to enhance the vitality of urban public space. The main conclusions include: 1) both explicit and implicit vitality show the characteristics of comprehensive parks＞special parks＞community parks, the spatial distribution of high and low values of explicit vitality shows the structure of "centre-periphery"; 2) explicit vitality and implicit vitality form four types of high and low values, which are the same as those in other urban public spaces. 3) Hidden vitality has a positive influence on explicit vitality, and user evaluation plays a partly intermediary role in the process of manifestation of hidden vitality.
