Abstract: As an intermediate link in the three-level heritage protection system of City–Block–Relic, the historical and cultural block is the most important part. As a component of a city, the vitality of historical and cultural blocks is related to the quality of urban space and the inheritance of cultural memory, and it is of great significance to urban renewal and sustainable development. However, traditional urban vitality evaluation methods need to deal with a large number of complex data, and it is often challenging to take into account the dual characteristics of space and culture. Traditional data and independent analysis strategy cannot not function well anymore. Therefore, this study proposes a vitality evaluation model based on multi-source data, which can account for the dual characteristics of space and culture, carry out dimension-reduced analysis for complex elements, so as to display the vitality image and indicate the key influencing factors of the block vitality. This maybe of important significance for exploring the internal dynamism of historical and cultural blocks. Firstly, guided by the “space-culture” composition of historical and cultural blocks, a wide variety of multi-level complex influencing factors of the vitality can be summed up to establish a three-layer vitality evaluation model. Secondly, the integration of multi-source data is realized by using the digital platform and giving out vitality pictures of the block. In this process, the Changmen historical and cultural block of Suzhou is taken as the sample for empirical research. Finally, the evaluation model is verified by combining the field investigation and the external representation of vitality. The calculation results are compared with the external manifestation of vitality, demonstrating the critical influencing factors of the vitality of public space in historical and cultural blocks, pointing out the direction for the creation of a residential environment and the promotion of vitality in the blocks.
