区域入境旅游流与航空运输网络协同演化规律及差异是值得研究的问题。文章探讨了入境旅游流与航空运输网络空间演化的协同关系和动力机制,并利用相关分析、回归分析和重心模型,从入境旅游流和航空运输网络的客流关联度、空间结构、网络结点连接强度等层面,对1999～2009年西南地区入境旅游流与航空运输网络的协同演化规律及差异性进行深入分析。结果显示:(1)西南地区入境旅游流与航空客流之间具有显著的相关关系,互动效应明显,但入境旅游流对航空客流的促进作用更强;(2)入境旅游流和航空客流的空间结构变动特征和趋势表现出较高的一致性;(3)入境旅游流和航空运输网络中的结点连接强度存在着较强的耦合性,其耦合程度受到了其它交通运输方式的影响;(4)西南6省区中仅有西藏的入境旅游流流量与航空客流量相关关系不显著,而其他5省区则较显著,但区域内部也存在较大差异。

One of the typical characteristics of inbound tourist behavior is that tourists often travel for a long distance in the tourism destination and choose efficient and convenient transportation mode.Air transport,a timely,convenient,efficient and comfortable mode,is playing an increasingly important role in inbound tourists' travel.As a result,airport becomes an important and basic condition for cities to develop inbound tourism industry.Improvement in air transport condition can enhance the possibility of inbound tourists' entry.Meanwhile,growth of inbound tourist flow also results in increasing demand for air transport,which in turn improves the flow efficiency of inbound tourists. Although there is a close relationship between inbound tourism industry and air transport,there have been few researches on disparities and co-evolution between inbound tourist flow and air transport network.This paper firstly analyzes the mechanism of spatial evolution between inbound tourist flow and air transport network,then constructs mechanism model of co-evolution,and studies the disparities and characteristics of co-evolution from 1999 to 2009,which concentrates on the network feature of flows,spatial structure,and node linkage. The conclusions imply that inbound tourist flow and air passenger flow are increasing in Southwest China,and there is a strong correlation(Pearson=0.963).The change characteristics and trends of spatial structure are consistent.In addition,there is a strong coupling relationship in the network node linkage.But Tibet has no obvious interrelation between inbound tourism flow and air passenger flow,and its correlation level is low,while other areas have significant interrelation along with a great internal difference.Therefore,air transport condition in Southwest China should be improved based on the spatial dynamic change of inbound tourism flow.Besides air transport links should be enhanced between provinces to improve flow efficiency of inbound tourism flow and comprehensive tourism benefit.
