Based On Reachability Analysis Of The Tourist Attractions Of The Nanjing Road Network Structure

With the rapid development of tourism industry and living pace, residences increasingly improved its requirements of tour convenience. This paper applied accessibility to tourism study and broadened its research arena to explore scenic spots accessibility calculation and analysis information system which was based on minimal pass-time oriented optimal route arithmetic. Based on the Nanjing road networks, this paper undertook empirical research in terms of accessibility of scenic spots in Nanjing downtown areas so as to generate mark Diffusing figure, Time contour, Service scope figures for scenic spots as well as Rank distributing figures of accessibility.Though analyzing these figures and charts, the author found that the accessibility of Nanjing scenic spots as a whole is satisfactory, with over 88% regional accessibility maintaining less 45 minutes. However, the inner difference gap is obvious, for the fact that the accessibility of downtown areas is much more superior to the outermost boundary which has reached 103min39s to some extent. Though ranking analysis of the whole accessibility in terms of villages and towns administration unit, a Circling-layering spatial structure focused by downtown area in terms of the regional distributing accessibility could be obtainedDue to the disequilibrium of inner-regional accessibility, the paper suggested that government should quicken the pace to build the peripheral scenic spots, to optimize its spatial distribution, and to perfect the planning of scenic spots in recreational belt around metropolis, and the construction priority should be given to Liuhe, Pukou and Jiangning districts of Nanjing for the consideration of poor accessibility.
