摘　　要：在实地调研的基础上,以西藏地区下辖的73个县域单元行政中心为点状要素,以干线公路为线状要素,采用地理网络的图论描述方法,构建西藏旅游线路抽象图。计算回路数、回路率、线点率、连线率、最大回路数和最大连线数等指标,对主体旅游交通线路进行定量评价。结果表明:西藏旅游线路在对外联系度、环线建设和路面质量等方面存在不足,难以满足旅游业快速增长的需求。旅游路网密度低,复杂度低,稳定性较差,区域差异显著,不利于旅游活动的组织。最后提出了西藏旅游线路优化策略。On the condition of spot investigation, taking 73 counties＇ center as point elements and trunk roads as line elements, the paper constructs abstract graph of tourism routes by way of graph theory. It also calculates some relative indexes, such as the circle number, circle ratio, line-point ratio, linkage ratio, maximal circle number and maximal linkages to make quantitative evaluation. The results show that there are apparent limitation of tourism routes, especially in external relationship, loop line construction and road surface condition, which is difficult to satisfy the rapid soaring demand of tourism industry. In addition, tourism road network＇ s density and complexity are low while its stability is comparatively poor and regional disparity is significant. All these conditions are unfavorable for the organization of tourism activities. At last, it proposes optimization strategies for tourism routes in Tibet, including promoting transport capacity of aviation and railway, improving the connectivity and stability of tourism network, accelerating the construction of tourism loop lines and actively promoting the construction of interregional lines.
