The coupling between the tourism flow (TF) and regional transportation (RT) plays an important role in the regional tourism market development and cooperation.Based on the big data of the TF and RT of the five Northwestern provinces from 1995 to 2014, the comparative analysis of evolution with respect to the coupling coordination between TF and RT during this time period and its spatial pattern are analyzed by adopting the coupling coordination degree evaluation model and GIS analysis.The results show that: (1)The comprehensive development level of TF and RT evolves from low to high, the overall standard deviation is 0.251 and 0.294, respectively, and regional gap appears gradually obvious;(2)The coupling coordination between TF and RT shows rising volatility and convergence of diachronic development trend, and the overall standard deviation is 0.173, but the gap between different regions gradually expands;(3)The global pattern of TF and RT coupling coordination experiences a transition from serious imbalance to primary coordination, nevertheless, the coupling coordination of different regions exhibits a trend from convergence to divergence, and eventually enters a "dumbbell" development pattern.Our results provide a theoretical reference to promote the regional tourism cooperation in Northwest China.%旅游流与区域交通系统的耦合发展对区域旅游市场开发与合作具有重要作用.基于西北5省1995~2014年旅游流与区域交通系统的相关数据,采用耦合协调度模型与GIS分析法,对西北5省旅游流与区域交通系统耦合协调度的时间演变特征与空间格局进行了历时态与共时态比较分析.结果表明:(1)西北5省旅游流与区域交通系统综合发展水平曲线呈现由低向高演进的态势,总体标准差均值分别为0.251和0.294,且区域内部差距逐渐凸显;(2)西北5省旅游流与区域交通的耦合协调度演变曲线呈现历时性波动上升且趋同发展态势,总体标准差均值为0.173,且区域内部差距逐渐扩大;(3)西北5省旅游流与区域交通耦合协调度类型实现了由严重失调向初级协调的转变,耦合协调度由低层次趋同向高层次趋异演变,并最终演变成"哑铃型"的发展格局.
