The Evolution of Urban Tourism Service Ability Pattern under the Influence of Highspeed Rail:The Case of the Yangtze River Delta
利用2007、2010、2013年铁路网络数据，结合GIS和Huff服务能力模型，研究高铁对长三角城市旅游服务能力格局的影响，发现高铁强化了核心-边缘结构但无法根本改变旅游城市圈空间格局。
This article has built a railway network dataset which is composed of 2007,2010 and 2013 three time sections,and uses GIS and Huff's service ability model to study the evolution of urban tourism service ability pattern under the influence of high-speed rail. The study found that: 1The high-speed rail has an obvious node and corridor lock-in effect on urban tourism service ability in the Yangtze River Delta, meanwhile, tourism service ability spreads from Shanghai and South Jiangsu to cities in the north of Zhejiang, which have promoted the relative balance of the core region. 2Tourism service ability in the Yangtze river Delta has formed a typical core- edge pattern under the influence of highspeed rail. 3 The influence of high- speed rail on the urban tourism service pattern has certain limits. It cannot fundamentally change the tourism city circle's spatial pattern, but it is the necessary condition to prevent comparative advantage decline. 4Combined with the ever found, the power-law distribution and fractal characteristics which exist in the hierarchical order of the pattern further strengthens that maybe widely spread in tourism.
