Research on the analysis of tourists' spatiotemporal behavior based on constraints

With the construction of Hainan Province as an international free trade port, tourism revenue will become one of the main sources of economic income in Hainan province. The study of spatial tourism flow characteristics in the region will help further develop and standardize tourism resources. The prediction of spatial tourism flow in the region is not only related to factors such as weather, transportation, scenic spot popularity, and consumption level in the region, but also restricted by space-time constraints. Especially with the rise of "smart tourism", spatial tourism flow has stronger nonlinear characteristics. Therefore, the research will analyze the spatiotemporal behavior of tourists from the aspects of space and time, and provide guidance for Hainan Province to effectively optimize the tourism spatial structure and formulate supporting tourism marketing strategies. This article focuses on analyzing the spatiotemporal behavior of tourists under constraints, establishing a multi-stage model of tourists' travel spatiotemporal behavior under constraints, and providing basic support for regional tourism flow trend evaluation based on time-varying and multi-source data under constraints.
