中文摘要：

通过构建入境旅游流与省域目的地耦合系统指标体系，对2000、2005和2010年我国西部12省（区市）两系统耦合协调度及其时空分异特征进行了定量分析。结果显示：①我国西部省份入境旅游流与目的地耦合协调发展水平缓慢提升，但仍未进入协调发展阶段。②入境旅游需求发展滞后为普遍现象，即有效需求不足是制约西部入境旅游发展的关键问题，而供给发展滞后省份数量呈现扩大趋势。③耦合协调度空间分异格局特征为，胡焕庸线经过及其以东省份耦合协调度水平较高，而以西省份水平较低。④耦合协调度的区域差异逐步扩大并呈现出两极分化的趋势，其主要原因在于入境旅游流系统发展水平差距的扩大，而且，旅游区内部省际差异，是整个西部地区耦合协调度总体区域差异的主要来源，其中又以西北地区省际差异为主。

英文摘要：

The paper constructs coupling evaluation model and index of two systems, evaluats coupling coordination degree of 12 provinces of western region in three years （2000, 2005, 2010） and its spatio-temporal differences. The results show： （1）The coupling coordination development level of inbound tourist flow and destination slowly improve in western provinces, but not yet reach the coordinated development stage. （2）The demand development of inbound tourism lagging behind the supply is a common phenomenon, which means that the lack of effective demand constraint is a key issue of the tourism development in western region, however, the number of supply development lagging behind the demand provinces is widening. （3）The regional spatial structure characteristic of coupling coordination degree is that the provinces of higher level are on Hu Huanyong Line and those which located on its east, while those ones on the west are lower. （4） The regional differences of coupling coordination degree is gradually expanding and showing the trend of polarization, mainly due to the widening gap of inbound tourism flow system development level, moreover, provincial differences within the tourist area, is the main source of the overall regional differences of entire western region coupling coordination degree, and in which northwest provincial differences is main.
