江苏旅游经济时空演变特征分析

运用区位熵方法,选取2000、2005和2007年3个时间段的旅游相关数据,从空间演变格局和内部不同尺度的差异变换情况2个角度,分析江苏旅游经济发展水平的时空演变特征,结果显示：①就空间演变格局而言,随着时间的推移,江苏旅游经济的发展经历了集聚众多—分散减少—稳定不变的演变形态;②就旅游经济的发展差异而言,近年来江苏旅游经济总体差距并没有拉大,主要是区域内部之间的此起彼落导致了差距变动,根据各自波动情况,将其分为4类,即稳定型（无锡、徐州、连云港和泰州）、增长型（淮安）、波动型（南京、常州、苏州和扬州）和衰退型（南通、盐城、镇江和宿迁）。

The Temporal and Spatial Evolution Characteristics Analysis of Jiangsu Tourism Economy

Using the location entropy methods,three time periods side of tourism-related date of 2000,2005,2007 were selected,from the angle of the spatial pattern and the evolution of the differences within the different scales,the spatial and temporal evolution characteristics of the economic development level of Jiangsu were analyzed. The results showed that from the aspect of spatial evolution pattern,as time goes on,the economic development of Jiangsu tourism has experienced morphological evolution of concentration-dispersion decrease-stability; when it comes to the development of the tourism economy,in recent years,the overall gap between the tourism economy in Jiangsu did not widen,the gap mainly led by the region one after another. According to their volatility,it will be divided into four categories: Stable type (Wuxi,Xuzhou,Lianyungang and Taizhou),Increasing type (Huaian),Fluctuations type (Nanjing,Changzhou,Suzhou and Yangzhou) and Depression type (Nantong,Yancheng,Zhenjiang and Suqian).
