长江三角洲城市一日游的旅游经济空间联系测度与分析

本文通过计算长江三角洲中心城市的中心职能强度,对长三角中心城市进行等级划分,在此基础上,借助修正后的旅游经济联系强度、旅游经济隶属度及旅游吸引范围模型,测度城市间旅游经济的联系强度、隶属度及城市旅游控制范围,同时建立城市旅游经济联系的空间模型并分析长三角中心城市旅游经济联系的方向以及旅游系统空间结构等级层次性特征。结果表明:长三角中心城市旅游经济联系度不断增强,并逐渐向区域旅游经济一体化方向进展,同时区域内部城市旅游经济差异显著,且表现为随着旅游城市等级规模的变化呈现出正相关的旅游经济随之匹配,并在旅游经济的空间联系上按照一定的轴线发生关系,这种轴线在地理空间上表现为"沿线"并且这种联系的规律性在空间上总的方向表现为随城市距离增加而逐级递减规律。基于以上分析,最后针对城市间的旅游经济空间联系对长三角旅游系统空间结构影响加以论述,以此为提升长三角城市一日游的旅游经济活动效率,加快实现长三角旅游经济一体化进程,提供一定理论与现实的依据参考。

MEASURE AND ANALYSIS OF SPATIAL LINKAGE OF TOURISM ECONOMY OF DAY TOUR OF THE CITIES IN THE YANGTZE RIVER DELTA

The Yangtze River Delta is a rapid developing gold zone of tourism economy, therefore, it is significant to analyze the urban economic space travel links and the core tourism cities. The result shows that the strength of tourism economic linkage between cities in the Yangtze River Delta is intensifying and extending to the integration of regional tourism economy. Meanwhile, it shows distinct difference in tourism economy between cities inside the Yangtze River Delta. And it presents positive correlation with the change of the hierarchic ranks of the cities. Moreover, it has relations in the spatial linkage of tourism economy according to particular axis which presents as "route" and the law of this link is that decreasing with the increasing distance between cities. The authors also divide the Yangtze River Delta economic circle into small tourism economic circles according to the calculated data, which are the coastal tourism economy circle centered by Shanghai, Taihu Lake tourism economic circle centered by Suzhou, the West Lake tourism economic circle centered by Hanghzou, in order to analyze the relationship between the tourism economic circles and adjust the complementarily of different circles. So the interaction within the Yangtze River Delta economic circle will be enhanced and greater tourism scale benefit will be achieved. Therefore, the spatial structure of the Yangtze River Delta tourism system will evolve more reasonable. Also, a wide range of markets and resources will be provided for special day tour in the cities and different tourism products could be designed for different tourists' demand. Based on the analysis above, the paper discusses the influence that the tourism spatial relationship between the cities has on the Yangtze River Delta tourism system spatial structure.
