在总结我国入境旅游流空间流动模式的基础上,依托市场调查和权威部门统计数据,以北京入境旅游流为研究节点,对其分级扩散模式和动力机制进行了分析。从结果来看,北京入境旅游流的一级扩散受到旅游者动机及我国旅游形象的影响,主要流向陕西、上海、辽宁和广东等省市;北京入境旅游流的二级扩散主要表现为两个方面特征,一是东部沿海地区的二级扩散旅游流主要流向为直接出境,二是西部内陆地区的旅游流主要扩散方向为东部沿海口岸省市:总体来看,目前以北京为口岸的入境旅游流还依托着我国传统的精品旅游线路进行扩散和流动,其他新兴目的地对入境旅游流的吸引作用还相对较弱;北京入境旅游流扩散主要受到内驱力、推力、拉力和阻力的共同作用,其中内驱力最为明显,而随着旅游流的扩散的不断延续一级时间的推移旅游流动力因素逐渐减弱,阻力因素不断增强,总体呈现出旅游流流势的距离、时间衰减效应。
From the domestic diffusion point, affected by tourists' motivation and China tourism image, the main stream tourists who continue in the domestic flow to Shaanxi, Shanghai, Liaoning and Guangdong provinces, it presents to be oriented by resource and economy under the influence of physical distance. As to the second level diffusion of Beijing inbound tourists' flow, the paper chooses major cities in Bohai Rim, Yangtze River Delta, Pearl River Delta, Xi'an, Chengdu-Chongqing and Yunnan, Guizhou and other typical tourist area to analyze. The results shows that after staying in the eastern coastal provinces of Jiangsu, Zhejiang, Shanghai, Liaoning, Guangdong and other, Beijing inbound tourists' flow mainly gathers in Beijing, Shanghai, Guangzhou and other core port cities, then is ready to exit. After staying in western Shaanxi, Sichuan, Chongqing, Yunnan, Guizhou and other provinces and cities, the tourists mainly flows to the provinces and cities like Beijing, Shanghai, Guangzhou and other coastal ports. Overall, the second level diffusion of Beijing inbound tourists' flow shows a clear exit trend. From the proliferation dynamic mechanism for Beijing inbound tourists' flow, the overall subject to the effects of the internal driving force, thrust, pulling force and resistance, which the driving force is the most significantly. Combining with the tourists' personal characteristics, leisure time, discretionary income and other conditions, the paper determines that tourists' flow trend has a strong distance and time decay effect.
