Based on the data of tourism sampling check from 1999 to 2003 in China, and in the context of spatial field effect,this psper
uses factor analysis to show the basic character of domestic tourist flows origin, distribution, centralization, decentralization and their relativity of tourist flows spatial network. The results are as follows: (1) Economy is the main driving force of the tourist flows origin, the effect of cultural driving force is intensifying and tourist resource is the main driving force of the tourist distribution. Now, China has formed four tourist flows original fields and five tourist destinations. (2) Influenced by market principle, the hierarchical structure of tourist centralization fields and decentralization fields represents the spatial sequence model of K = 3. (3) The regional structure of tourist centralization fields show the character of "U" form, and the regional structure of tourist decentralization fields represent the pattern of "third class ladder". (4) The spatial network indexes of β and γ indicate that the relativity of tourist flows spatial network is feebleness. Finally, the paper regards that China should expedite the tourism development of the "two zones & three regions", namely the two zones of the Yangtze and Yellow river drainage areas and the three regions of the south coastal provinces, the north coastal provinces and northeast provinces in China. They are the key directions to push energetically the cooperation among tourist regions, endeavor to construct the tourist spatial network system, adjust and optimize the directions and quantity of tourist flows, as well as the key factors to enhance the network level of tourist flows.
