Abstract:

Tourism destination circle(TDC) is a kind of destination region, which is defined as a spatial collaborating organization, which inhabits a certain geographic space, and has one or several tourism distributing centers as well as many tourism areas (or tourism attraction complexes), It can supply enough products and services for an effective visit. Here, the scale of an optimum TDC is of vital importance: If the scale is beyond the actual demand of visitors, then the TDC is inefficient and some tourism resources (or products) are wasted; if the scale is less than the actual demand of visitors, then the visitors cannot be fulfilled and the TDC cannot develop well. In this paper, tour-time (T, including traveling time T0 and visiting time T1, unit: days) and tour-diameter (?渍, unit: kilometers) are introduced to measure the scale of TDC, in which tour-time is a scale from temporal dimension while tour-diameter is a scale from spatial dimension. Two computable models on the scale of an optimum TDC are proposed based on statistical analysis of the data gathered from more than 600 travel itineraries, which are applied in the Yangtze River Delta as an example. The research shows that: 1) There is a high significantly positive correlation between the scale of an optimum TDC and the traveling distance (D, unit: kilometers), in which T1 = 0.0715D0.5655 and T0 = 0.1908D0.4601, while ?渍 = 0 (if  D ≤322) or ?渍 = 253.6lnD - 1464.6 (if D > 322). 2) When we consider only market factors, the demand of tourism market within 300 kilometers from a destination region is the basic force for the development of tourism areas, and then the formation and expansion of TDCs are induced by the demand of tourism market beyond 300 kilometers from the destination regions. The increase of TDC is convergent, which should be less than 600 kilometers. 3) The scale of TDC will "transfer" from one state to another based on "time-space linkage" between continuous tour-time and discrete tour-diameter, which leads to the formation of a nested structure of TDC.
