ABSTRACT
While domestic cities are developing rapidly, they are facing poor urban spatial vitality. At the same time, the development of the information age has made the structure and function of cities more complex and changeable. People have proposed higher directions for the comfort of urban space. In the context of big data, multi-source data can be used as the main element of urban spatial vitality assessment. This paper uses urban spatial data, urban POI data, and urban spatial heat map data to evaluate and analyze the spatial vitality of the built blocks in the West Lake East Area of Shangcheng District, Hangzhou from the two dimensions of time and space. The results show that: (1) The combination of multi-source data can more comprehensively reflect the characteristics of urban space vitality. (2) The four basic functions of residence, transportation, work and rest are interdependent. (3) In future urban planning, attention should be paid to the matching degree of various facilities and the corresponding supporting facilities of the flow of people.
