长三角地区旅游城市体系组织秩序信息维数研究

Research on Fractal Information Dimension of Tourist City Systems′ Organization Order in Yangtze River Delta

对长三角地区旅游城市体系的旅游功能进行量化处理,采用分形方法研究其组织秩序来考察旅游城市体系对旅游活动的支撑作用,通过对长三角旅游城市体系组织秩序的信息维数的测算与分析,认为长三角地区旅游城市体系组织秩序具有较好的分形特征,系统结构比较紧致,各城市之间的整体性较好,对旅游活动的支撑作用较强.无论北部子系统还是南部子系统,上海在其体系中均具有很强的中心辐射作用,但也存在一定的差异,上海市对南部旅游城市体系旅游功能的加强程度要高于其在北部旅游城市体系中的作用.在目前条件下,上海还不足以带动整个长三角地区旅游城市体系整体性的提高,因此,加强上海的中心辐射作用,是使之成为实现长三角旅游城市一体化程度提高的重要途径.

By the application of fractal method,this paper measures the fractal information dimension of organization order of tourist city systems in the Yangtze River Delta,in order to examine the supporting role of such systems in tourism.Results indicate that for the whole study area,the organization order pertains relatively typical fractal features,reflecting in following facts,for example,the systems are quite compact in structure and the integrity of various cities in study area is relatively good.These features show a relatively strong supporting role to tourism activities.It is clear that both in the northern or southern sub-systems,Shanghai is playing the role of strong centre or hub for the whole area in tourism development,especially in the southern sub-system.However,under current conditions,Shanghai is still not strong enough to improve the general integrity of tourist cities in the delta region.Therefore,the strengthening of Shanghai′s central function would be one of the important ways in the improvement of such integration.
