湖北省旅游交通可达性及旅游经济联系空间分析

运用加权平均旅行时间，结合引力模型对湖北省旅游交通可达性以及旅游经济联系量空间差异进行分析。结果表明：（1）湖北省旅游交通可达性在空间上呈现出以武汉为中心逐渐向周边递减的圈层式空间格局；（2）旅游经济联系空间差异显著，具有“东密西疏”的空间特征，武汉城市圈旅游经济联系较为紧密，空间网络化明显，鄂西生态文化圈旅游联系较为稀疏；（3）旅游经济联系总量地域差异明显，武汉城市圈旅游经济联系总量远高于鄂西生态文化旅游圈；（4）旅游交通可达性与旅游经济联系量相关性明显，其组合状况在空间上呈渐进式阶梯状的空间分布特征。

Spatial Analysis of Transport Accessibility and its Correlation with the Tourism Economic Linkage of Hubei Province

It is closely associated between road transport accessibility and external economic links, and good road transport acces- sibility contributes a lot to the development of tourism. By adopting the methods of weighted average travel time and Gravity mod- el, this paper attempts to investigate the transport accessibility and the spatial difference of tourism economic linkage in Hubei Province. The research results show： （1） The transport accessibility of Hubei province shows the Wuhan--centered spatial pat- tern gradually disminishing around in space. （2） There is great spatial difference in tourism economic linkage, dense in east while sparse in west. The tourism economic linkage of Wuhan Metropolitan Area is featured by close contact and obvious spatial net- working, while loose contact in Exi eco--cultural tourism circle. （3） The total amount of tourism economic linkage displays sharp difference in Hubei province. Tourism economic linkage of Wuhan Metropolitan Area Account for 83.8% of Hubei Province, far higher than that of Exi eco-cultural tourism circle. （4）The road transport accessibility and tourism economic linkage is obviously correlated, and the combination is gradual and ladder--shaped in spatial distribution.
