良好的旅游交通通达性是旅游资源开发和旅游地建设的必要条件，对目的地的运营和稳步发展至关重要。应用通达性指数和社会网络分析方法中的点度中心度、中间中心度、平均最短路径长、网络密度、中心势等指标，对西安目的地内部45个旅游景点和10个交通口岸的旅游交通通达性进行了定量研究，得到：（1）旅游交通具有不同于普通交通的特殊性，不能简单地用普通交通通达性指数来衡量旅游交通通达性。（2）社会网络分析法中的度数中心度、中间中心度和平均最短路径长分别是度量目的地内部各景点之间或交通口岸到景点之间点对点便利度、中转便利度和全网直达便利度的合适指标，网络密度、程度中心势和中介中心势等指标是衡量目的地内部旅游交通网络发育程度的合适指标。（3）虽然西安目的地内部景点之间、交通口岸与景点之间的交通道路连接水平较高，但公交线路包括旅游专线数量和分布状况、机场大巴站点数量和设置位置等不能完全满足散客旅游者的需求，旅游交通便利程度有待提高。（4）西安目的地内部景点的分布具有大分散、小集中的特点，亟待通过改变偏远景点与市区景点之间的交通连接方式提高偏远景点的旅游交通便利程度。（5）在国际和国内旅游市场日益散客化的形势下，旅游城市的交通规划应重视散客旅游者的交通需求。提出了新的旅游交通通达性评价视角和指标。%This paper adopts accessibility index and the social network analysis to conduct a quantitative research on the traffic accessibility of Xi'an′ scenic spots . The main results are as follows :(1 ) Compared with the normal traffic tourism traffic has its own specificity , which can not be simply measured by the traditional accessibility index of traffic . (2 ) According to the social network analysis methods , the point centrality , the betweenness centrality and the average shortest path length are the appropriate indicators to measure the point‐to‐point convenience , the transit ease and the network‐wide direct convenience . And there are some appropriate indicators to measure the development degree of the internal tourism traffic network , such as the network density and the network centralization index .(3)Although the traffic connection level between internal attractions ,the transportation ports and the scenic spots are good , the bus routes cannot completely meet the requirement of individual tourists , in particular , the number , the distribution of tourism special lines and the number of the airport shuttle bus sites and position need be improved .(4 ) Xi'an scenic spots are dispersedly distributed with localized concentration feature ,so it is urgent to adjust the traffic connection between remote scenic and inner spots to make it convenient to travel to those remote scenic spots .(5)Due to the tendency of increasing individual travelers according to both in international and domestic tourist market ,a tourist city's traffic should adapt to the demands of individual travelers .
