都市旅游圈是具有一定向心性和层次性的旅游经济地域系统。基于对相关概念及研究的梳理,本文认为都市旅游圈形成和演化是都市旅游跨界拓展和区域旅游合作性竞争及趋向一体化发展共同推动的产物,空间集聚与扩散作用是都市旅游圈空间结构嬗变的主要动力,并以上海和长三角为例探析了都市旅游圈空间结构网络化(多核心+互动)发展,即通过景区(点)、交通、产业、市场等各个子(分)网络共同构成互补、协作和竞争的大旅游产业体系,不断推动都市旅游圈发展壮大。
Urban tourism circle is a kind of regional tourism economic system with characters of centrality and hierarchy.On the basis of studying related research,the author assumes that the formation and evolution of urban tourism circle is the joint result of both trans-boundary development of urban tourism and integration of regional tourism,and spatial diffusion and agglomeration are the main powers that promote the transmutation of spatial structure of urban tourism circle.Finally,by taking Shanghai and Yangtze River Delta as examples,the author explores the networking development(multinuclear + interactive)of spatial structure of urban tourism circle which is a grand tourism industry system built by many subsystems.
