| Tourism destination circle as an important feature of regional tourism cooperation,its development is inseparable from the geographical space.Since the introduction of the Tourism destination circle,the spatial structure and evolution of the Tourism destination circle have been widely concerned by scholars,and the theory of the spatial structure of the Tourism destination circle has gradually matured.However,the current research is mostly based on the combination of subjective judgment and qualitative analysis,quantitative analysis and endogenous explanation;In addition,the "protagonist"members of the Tourism destination circle form the core area of the Tourism destination circle,its spatial model and evolutionary expansion to tourism The spatial process of the circle has a decisive effect,but for a long time academic research has paid less attention to it.Based on this,this paper adopts the cognitive system of "nested ring layer structure" model and takes the patch layer(the core area of Tourism destination circle)as the breakthrough,(Spatial horizontal axis)and the spatial evolution process(time longitudinal axis).The paper discusses the spatial organization and evolution of the Tourism destination circle in order to further enrich the Tourism destination circle theory.This study collects the tourist route data of the tourist website and uses the method of social network analysis to try to quantitatively identify the spatial structure of eight provincial scale Tourism destination circles,such as Hunan and Jiangxi.The study found that:in terms of spatial structure,the Tourism destination circle is manifested as two typical spatial structure patterns of karyotype and binuclear type.In terms of spatial combination,the core area of Tourism destination circle is the different combination of tourism "city" and tourism "portal" city.In terms of space scale,the spatial scale of the Tourism destination circle has a certain regularity,usually composed of 4-5 cities.But this spatial organization model is not immutable,it continues to evolve over time.In practice,the Tourism destination circle is often manifested as the organization process of the tourist routes.Therefore,this paper takes the tourism utility of the tourist routes as the starting point,and theoretically discerns the spatial structure and evolution of the Tourism destination circle.It is found that there is a" widening area" in tourism activity in practical tourism activities,which is of great significance to the development and evolution of Tourism destination circle spatial organization.On this basis,this study attempts to put forward the conceptual model of the spatial evolution of the Tourism destination circle.In theory,there are two modes of space organization,namely,single-core structure model and dual-core structure model(including two cases,And dual-core mode 2).From the time point of view,the single-core structure model with the passage of time may evolve into a dual-core structure model,it is possible to remain unchanged,continue to nest in the nest on the development of sub-Tourism destination circle;dual-core structure model 1,the two The core may develop into a core,there may be two core division,the re-development of tourism to form two independent Tourism destination circle;dual-core structure model 2,nested in the two core of the sub-Tourism destination circle has emerged and independent development,In the middle of the two sub-Tourism destination circle "vacuum area" of the tourist destinations to seize the advantages of third parties,the Tourism destination circle of space model have a significant impact on the formation of the Tourism destination circle of the "third pole" tourism domain.Of course,there are some shortcomings in this study.In reality,the spatial organization of the inter-provincial Tourism destination circle is worth exploring further.At the same time,the conceptual model of the spatial evolution of the Tourism destination circle needs to be further verified by further realistic data. |
