| Along with 20 years of the process of country reform and open policy, the tourism has great development, and there are inbound, outbound, domestic tourist flows, which are three different flows.According to inbound tourist flow, our country has occupied the fifth place in the world, and it also gradually increases in our country foreign exchange earnings proportion.Thus, the research of the tourist flow, especially the inbound tourist flow is more and more important.With the development of technology, the research of tourism needs high technique.GIS, wich is a high technology of geographical research, and is charactered as the spatial analysis, has more and more wide applied area. But the study of the tourist flow based on GIS is not enough, so the foundation of an inbound tourist flow information system has great academic and applied meaning.Based on the shortcoming, an inbound flow information system will be established. This system uses the function of thematic map in Maplnfo to demonstrate data, and uses the GIS technology to realize not only the general consultation function, but also data forecast function, to help decision-making.The work of the studies of inbound tourist flow will show as GIS. This article 's main content:(1) The Establishment of inbound tourist flows information system's frame: the analysis of the tourist flow has been made, and the modules of current situation and the forecast, the structure and function of each small module has been designed, meanwhile system connection, the interface, and the development environment has been designed too;(2) The research of MapX redevelopments: The research has been made to insert MapX in Visual Basic to design the tourist flow information system. The function of MapX has been used to realize the map editing, spatial analysis, data binding, and the map browsing to complete a GIS;(3) Spatial analysis has been researched: spatial analysis has been elaborated, and the mathematical models for statistical analysis have established;(4) Integration with Spatial statistical analysis and GIS: The method of the integration with the spatial statistical analysis and the GIS has been studied. In the practice, the statistical analysis software will insert the development platform. With theOLE, the SPSS will insert the development environment to realize the spatial statistical analysis function;(5) Thematic maps technology's utilization: with the thematic map function of MapX, the thematic map technology is utilized in the system to develop the MapX module to realize demonstration, revision, deletion, and increase of the thematic map;(6) The research of database function: Access, which enable the systme has the function of data inquiry and data browsing, and simplify the method of data input and data inquiry, realizes the data management function. With the inserted OCX in MapX, the databinding, the connection with map database and the attribute database, and the database mutual visiting is realized.After the trial test, the frame of inbound tourist flow information system in China is founded, and its function was been realized Initially. This system has realized the majority functions, which are data browsing, data statistics, etc, to serve for the tourist flow, and the conclusions follow here:(1) The GIS can unify the modern theory, which are statistics, cartography and GIS and so on in the tourist flow information system, and is one effective way to study the tourist flow information system. Tourist flow information system is one of the ways of GIS's application, and it can unify tourist flow information and GIS.(2) After practice, the establishment of inbound tourist flow information system in China is feasible, and it can provide a new way and method to research of the inbound tourist flow. It can prove the management of tourist flow information, and can develop the new way of the application of tourist information, can serve for the research of the ruler of tourist flow, policy of tourism, and the development of economy an...
