Based on the POI-related data of Quzhou City, Zhejiang Province in 2021, the standard deviation ellipse, center of gravity, kernel density analysis and other spatial analysis tools in the Arc GIS spatial analysis method are used to clarify the urban tourism in Quzhou from the aspects of quantity change, distribution characteristics, and agglomeration .The distribution law of leisure formats,and the formation mechanism of urban tourism and leisure formats in Quzhou is studied. The results show that: ① On the whole, the tourism and leisure formats in the central urban area of Quzhou show the characteristics of spatial agglomeration, and the agglomeration situation of surrounding counties and cities is not obvious. The central urban area, especially Kecheng District, is rich in related business formats, while the west of Quzhou and north of Quzhou are relatively sparse.② From the distribution of various formats, the standard deviation ellipse of each format moves in the southwest-northeast direction, and the distribution range of the accommodation service industry are relatively large. Extensive, but no obvious agglomeration center has yet been formed. The distribution direction of shopping service formats is not significant, and the catering service industry is highly dense. The average center of each format shows the spatial development characteristics of agglomeration in the city center. Most of the business formats are located in the main urban area of ?Kecheng District. ③ Judging from the agglomeration of various business forms, the central urban area has a multi-core development trend, and the surrounding counties have low-density point-like agglomeration. Catering services are concentrated in the urban hinterland of northeast and north of Quzhou, with similar distribution of outlets for shopping services, leisure and entertainment, and tourist attractions. Accommodation services are mainly manifested in the core radiation of the central urban area, while the distant urban areas are distributed in many spots surrounding tourist attractions. ④ From the perspective of the formation mechanism, the market environment, population size and traffic conditions are the decisive factors for the spatial distribution of tourism and leisure formats in Quzhou, and the interconnection within the industry is the potential kinetic energy of industrial development. Different influencing factors that influence formation and development of tourism and leisure business in Quzhou City are combined through market regulation and government macro-control.
