借用齐夫法则研究了江苏省近10年的旅游收入规模结构变化,并与差异度变化加以对比。结果显示无论是国内旅游收入还是国际旅游收入,规模分布均基本遵循齐夫定律,与差异度变化趋势也相一致;无标度区范围均呈扩大趋势,规模结构逐步得到优化。但两者也有不同点:(1)前者从局部单分形演变为几乎覆盖全域的单分形,而后者则从局部单分形→几乎覆盖全域的单分形→局部单分形→双分形;(2)前者是先呈帕雷托模式后呈不规则的帕雷托模式,而后者则是前几年呈不规则的帕雷托模式,后几年标度区一呈对数正态分布模式,标度区二呈不规则的帕雷托模式;(3)前者的规模变差是先扩大后缩小,而后者则是前几年规模变差略有波动,后几年两个标度区之间的差距稍有扩大,但各标度区内部的规模变差却呈缩小趋势。齐夫法则可为分析旅游收入规模结构变化提供新的定量方法。

Up till now, there are some studies on Zipf law and fractal theory used in tourism geography, but it lacks systematicness and needs to make a thorough study. There are many studies on tourism income such as the time and spatial difference of tourism income, the influence factors of tourism income, tourism income forecasting model, the connection between tourism income and regional economy, but there isn't a research on the scale structure of tourism income. This paper studied the variation of scale structure of tourism income in Jiangsu province based on Zipf law and compared with the change of difference degree. It tried to find the changing law of the scale structure to guide the tourism resource development sequence, and to provide theoretical support and practical direction for spatial distribution of tourism scenic sites and urban system of tourism nodes and for the building of strong tourism province in Jiangsu. The scale structures of domestic tourism income and international tourism income in Jiangsu province during 2000-2009 satisfy Zipf law in each year, and their changes of scale structure are both in accord with their changes of difference degree. The non-scaling ranges of scale structures of domestic tourism income and international tourism income both vary with a gradually expanding tendency, and the scale structures are optimizing gradually. However, the variation of spatial fractal,distribution pattern and scale gap is not synchronous. The spatial fractal of domestic tourism income varies from local single fractal to single fractal including almost the whole region, while international tourism income varies from local single fractal to single fractal including almost the whole region, then to local single fractal and to double fractal in 2006-2009.
