Abstract：The research on spatial pattern of urban catering industry is of great importance for urban planning and urban sustainable development. This paper focuses on the simplicity of the existing research methods and insufficiency on the qualitative analysis of influencing factors in the derivative studies. Coupling analysis between dynamic population and the spatial distribution of the catering industry is carried out through identifying the hot spots of catering in the main city of Wuhan using POI data and the hot spot index method based on nuclear density， and establishing the model of population activity intensity by combining the heat map of weekday with weekend from Baidu Map. The analysis shows that there are 1 primary center， 3 secondary centers and 9 tertiary centers of the catering industry in the Wuhan main city. The spatial distribution of catering industry generally matches the dynamic population with the matching degree of weekday slightly higher than that of weekend The regions with poor and even worse matching degree are scattered on the periphery of the large-scale commercial circles， the traditional small and medium-sized shopping districts， tourist spots， renewed blocks and emerging blocks depending on their specific types.
