摘　　要：久马高速公路作为联络西北至西南方向的大通道,也同时起到促进当地经济和社会发展,带动旅游观光的重要作用。以道路使用者的角度对久马高速公路沿线4个景观段落进行动态景观评价研究,从景观基底、景观视域、景观节点等方面选取11个评价指标,创建“面-线-点”3个层次的久马高速公路沿线动态景观评价模型,通过BIM+VR技术搭建数字孪生场景进行模拟驾驶体验和评价,利用层次分析法确定动态景观评价指标权重并对景观质量展开模糊综合评判。结果表明:久马高速公路沿线不同景观段落带给道路使用者的感受差异较大,其中动态景观质量极高的为多美花原景观段,较高的为绿峡花谷景观段,一般的为秘境花廊景观段和红原花海景观段,不存在质量低的段落。客观评估久马高速公路沿线各个景观段落的质量,为地方相关部门指导该高速公路沿线景观管理、打造、开发、决策和旅游业的发展提供参考依据。The Jiuzhi-Maerkang(Jiu-Ma)Expressway,as a major channel connecting the northwest to the southwest of China,plays an important role in promoting local economic,social development and driving tourism.From the perspective of road users,a dynamic landscape evaluation study is carried out on 4 landscape sections along the Jiu-Ma Expressway,1l evaluation indexes are selected from landscape basement,landscape horizon,landscape nodes and other aspects to create a dynamic landscape evaluation model along the expressway with 3 levels of“plane-line-point”.BIM+VR technology is used to build a digital twin scenario to simulate driving experience and evaluation,and AHP is used to determine the weight of dynamic landscape evaluation indicators and carry out fuzzy comprehensive evaluation of the landscape.The results show that different landscape sections along the Jiu-Ma Expressway bring different feelings to the road users.Among them,the dynamic landscape section with extreme high-quality is the Duomeihuayuan landscape section,the relative high-quality one was the Lyuxiahuagu landscape section,the Mijinghualang landscape section and the Hongyuanhuahai landscape section are ordinary quality,and there is no sections with low-quality.Objective assessment of each landscape section's quality along the Jiu-Ma Expressway can provide references for local relevant departments to guide the development of tourism along the expressway and landscape management,construction,development and decision-making.
