Studying the distribution of urban functional areas and the laws of population activities on a fine scale has important implications for the government and relevant departments to rationally adjust the allocation of urban internal resources and arrange the layout of urban facilities. Taking the center area of Shenyang City in Liaoning Province as research area, based on the principle of nuclear density estimation, the distribution of functional areas in downtown Shenyang is explored based on point-of-interest (POI) data, and the temporal and spatial distribution patterns of urban population on working days and weekends are explored by interpreting the multi-temporal Baidu thermogram data. This paper analyzed the spatial structure of Shenyang city center from two perspectives: the distribution of the urban physical facilities and the law of the population activities. Finally, we used SPSS to analyze the correlation between population heat and urban physical facilities and established multiple linear regression models. The results showed that: (1) Shenyang City vitality area showed a multi-center distribution model, mostly in the commercial center, financial center or urban function complex center. (2) The spatial distribution of the hot spots in the working day was more scattered than that on the weekend. The area was larger and fluctuated greatly. However, population hot spots were mainly concentrated in the commercial center and urban complex functional area and there was a large fluctuation during the daytime on weekend. (3) The distribution of functional areas was significantly correlated with the population heat. Life service facilities, financial facilities, transports, accommodation facilities and attractions are the main factors influencing the population heat on the working day. While educational institutions, transports, public service facilities, catering facilities and financial facilities are the main influential factors on weekend.
