440 travel notes on Silk Road （China section） are analyzed by Text Mining Method, and the research shows that the tour routes chosen by the tourists are mainly the route from Xian to Dunhuang, especially focus on Dunhuang, the tour traces are chiefly centralized in Gansu and Qinghai, but the routes from Luoyang to Xian and from Dunhuang to Xinjiang are less focused, however, the cognitive images of the tourism resources of the tourists on the Silk Road are relatively comprehensive, including both the humanities landscape as the grottos, the murals or the sites and relics, and the natural landscape as the desert, the Yellow River or the setting sun, therefore, the impression opinions tend to be positive and consistent. Local life experience becomes an important tourism activity, and the drivers play an important guiding role. Because the development condition and pattern of the regional tourism along the Silk Road are not uniform, Chinese Government should use different image construction strategies, the theme image construction along the Silk Road should follow the idea of “harmony and difference”, and the governments along the Silk Road should consolidate the construction of public culture space and public culture facilities while enhancing the guidance, supervision and training of the bus drivers for the route.
