中文摘要：

交通是推动旅游发展的重要＂引擎＂。伴随中国进入高铁网络时代,高铁＂时空压缩＂效应对区域交通可达性格局产生重大影响,进而引致＂哑铃型＂旅游系统或旅游＂人地关系＂体系中一系列区域旅游要素产生＂多米诺＂效应,尤其是高铁对旅游空间行为、旅游市场需求和客源结构、旅游资源吸引力格局、与其他交通系统竞合、旅游产业结构、旅游空间格局等方面产生的影响更加凸显,由此催生出旅游地理学研究的20个新命题。梳理这些新命题既能为系统性开展高铁旅游研究提供思想启示,又有利于推动旅游地理学学科发展和理论创新。

英文摘要：

Transportation has been a very important ＂engine＂ promoting the development of tourism. With China entering into the high- speed rail network era, ＂time- space compression＂ effect of high- speed rail has had a significant impact on the accessibility structure of the regional transportation, and thereafter, has a ＂domino＂ effect on a series of regional tourism elements in the ＂dumbbell- shaped＂ tourism system, as well as the tourism system of ＂humanenvironment interactions＂. More impacts are found on the following aspects as well： The tourism spatial behavior, tourism market demand and market structure, structure of the tourism resources attraction, competition and cooperation with other transportation systems, tourism industry structure, tourism spatial structure, etc. Hence I inspire 20 new topics in tourism geography research. Analysis of the new topics will not only provide some enlightenment on further research on high- speed rail tourism more systematically, but also accelerate the development of tourism geography and theoretical innovation.
