Abstract: Consumer service industry is an important part of service economy, and its rational distribution plays an important role in developing urban economy and meeting the consumption demand of residents.As an important point data representing urban spatial facilities, poi is a new data source to study the characteristics of urban spatial pattern. Based on poi data, the spatial pattern of consumer service industry in Changsha was studied by using the methods of kernel density analysis, entropy index, frequency density analysis and spatial clustering. It is found that the consumer service industry of Changsha is mainly influenced by traffic and urban planning. The whole distribution is "one core, four axes, multi-polarity", and the spatial distribution is closely related to population concentration, and the difference between east and west is obvious;The distribution characteristics of different types of consumer service industry are different, which are mainly "single core", "double core" and "multi-core" in spatial form. The distribution of functional diversity is characterized by the central periphery structure at the core of the Wuyi Square. The areas with diverse functions and high degree of mixing are located in the central city, and the consumer service industry in the peripheral area is weak and most of them are single-function or dual-function mixed areas.
