As the most important "linear" corridor in northwest China, Qinghai Tibet Railway not only plays an important role in promoting regional connection,but also has great sightseeing value. This paper has a evaluation about tourism dynamic landscape quality of 10 natural landscape belts along Qinghai-Tibet railway from tourists'perspective. Firstly, this paper gives an exact definition of evaluation object along the railway, and constructs "Tourist-Eye" evaluation model which is based on tourists' visual experience during the journey. Landscape matrix, including landscape diversity, animal and plant ornament and cultural landscape richness is the first thing coming into view. Which landscape can be captured by tourists depends on the vision field condition including the relative slope, probability of appearing in tourists' view, distance, etc. While, landscape aesthetic characteristics, like color, rare degree of landscape and water allocation, determine which landscape can impress tourists. Secondly, this paper builds an evaluation index system, consisting of three class and nine basic indexes which are selected and weighted through Analytic Hierarchy Process (AHP)and fuzzy comprehensive evaluation methods. The results shows that 10 landscape belts along Qinghai-Tibet railway differ significantly in landscape quality, and are listed below from high to low: Nyainqentanglha valley basin landscape belt, Kunlun mountain landscape belt, Kekexili-Yangtze valley landscape belt, Tanggula Mountain landscape belt, Nu River valley landscape belt, Qinghai Lake basin landscape belt, Lhasa valley landscape belt, northeast high mountain of Qaidam Basin landscape belt, Huangshui valley landscape belt and Gobi and Saline Lake of Qaidam basin landscape belt, among which there are one extreme high-quality, six relative high-quality, two ordinary quality and one low-quality landscape belt. Evaluation about tourism dynamic landscape quality along Qinghai-Tibet railway is able to inform tourists about landscape quality along the railway, provides basis for local sectors' tourism development and management decisions and improves the popularity of Qinghai-Tibet railway as well.
