基于新地理信息技术的南京市游客流动性空间特征研究

利用新地理信息技术,采集500个游客GPS地理标记照片,运用GIS空间分析方法,分析游客在南京城市内部及其与长三角其它城市空间流动特性,并提炼游客空间行为一般模式。发现:①南京城市内部旅游流在主城区集聚,整体上呈现中心城区向四周扩散的趋势;且在空间形态上形成小型化、斑块化的布局特征。②南京与长三角周边城市的线形路线以点-点模式为主导,地域模式以便利的同城市中心流动为多数,其旅游流流动模式与已有典型模式基本吻合,同时长三角地区旅游流呈现等级扩散特征。

THE SPATIAL CHARACTERISTICS OF TOURIST FLOWS IN NANJING BASED ON THE NEW GEOGRAPHIC INFORMATION TECHNOLOGY

Since 21st century, information technology has got rapid development around the world. The information technology is not only affects the human economic structure and social form, but also changes the global physical and virtual space structure. On the other hand, the city has become an essential resource in modern tourism, the space is also proved to be the important carrier and elements of tourism development, which makes the city become the significant tourist destination. In the age of information technology, the relationship between geographic information and entity space has become a hot research theme. Based on the geographic information technology, by collecting 500 visitors with their geo-referenced photos and using GIS spatial analysis method, this paper analyzed the spatial characteristics of tourist flows and identified visitor's spatial behavior patterns in Nanjing city and the Yangtze River Delta. First of all, according to the method of kernel density, tourist flow in Nanjing is concentrated in the urban area, including Qinhuai, Xuanwu, Gulou and Baixia these four districts, and shows a trend of spreading from the central urban district to the city outskirts, with characteristics of miniaturization and plaques in the spatial distribution. At last, Nanjing with linear route around Yangtze River Delta cities are dominated by point to point model, the regional flow patterns with the convenient city centers are for the majority, the tourist flow patterns are match with the authors of Alan Lew and Bob McKercher's standpoint who proposed three kinds of linear routes and four regional models.
