The 19th National Congress of the Communist Party of China proposed the strategy of rural revitalization, and the construction of beautiful countryside is an important way to realize rural revitalization. The study on the vitality of beautiful countryside provides the basis for the construction and planning strategies of beautiful countryside. Taking the beautiful village of Shitang Family in Nanjing as an example, this paper explored the spatial vitality characteristics of the beautiful village by mining Baidu thermal data and traditional planning data, established a quantitative analysis method for the spatial vitality of the beautiful village, and statistically analyzed the significance of various influencing factors. The results show that the spatial vitality of the beautiful countryside is different in the time dimension, which has a big diversity in the rural vitality between weekdays and holidays, while the vitality changes in weekends and holidays have the same trend, and the peak value in holidays is higher. In the spatial dimension, the population concentration which has a better-built environment in the rural areas is relatively high. In terms of influencing factors, public service facilities have the greatest impact on the vitality of beautiful rural spaces, followed by catering service facilities. Accordingly, the paper proposes corresponding planning strategies to provide the foundation for the construction of beautiful villages.
