中文摘要：

一体化是区域经济发展的必然趋势，区域一体化对城市旅游规模差异产生深刻影响。运用区域规模差异的相关指标和位序规模理论，对南京都市圈建设10年（2001—2010）的城市旅游规模差异进行分析。结果显示：都市圈城市旅游总体发展态势不均衡，旅游规模的绝对差异明显，但相对差异呈缩小态势；城市旅游规模首位度异常明显，城市旅游规模符合位序规模分布规律。都市圈城市旅游的总体格局未发生显著变化，区域旅游亟需深化合作，寻求协同发展。基于这一前提，从完善地区间的利益协调机制、借力行政区划调整、打造跨地区的特色旅游线路、建立健全区域旅游协作渠道、塑造区域一体化旅游形象等角度提出促进区域旅游协同发展的思路。

The integration is the inevitable trend to achieve scientific development of the regional economy, regional integration has a profound impact on the differences of urban toursim economy. Based on the relevant inde- xes of the regional diversity in the size and the theory of rank-size distribution, the paper makes an analysis of tourism size diversity and regularities of distribution in 8 cities of Nanjing Metropolitan from 2001 to 2010. What the results show as following ： the level of tourism development is extremely not balanced, and unbalanced structure is relatively stable in 8 cities of Nanjing Metropolitan since 2000 ; the primate city distribution of tourism scale is highly concentration, the first degree of Nanjing makes a downward trend;the city tourism scale consistents the system of rank-size distribution, but there is considerable potential for development. The metropolitan city tourism scale over-all pattern has not changed significantly, the regional tourism needs deepening cooperation, seek synergistic development. from the Based on this, the paper angle of improvement of tive divisions, building regional c forward the train of thought of coordinating development of regional tourism terest coordination mechanism, leveraging the adjustment of administratourism line, establishing and perfecting the regional tourism coopera- tion channels, shaping the regional integration of tourism image.
