Theoretical discussion and dynamic evaluation of the"spatial equilibrium"evolution of tourism ecosystem:A case study of four world natural heritage sites in Guizhou
Scientific measurement and examination of the"spatial equilibrium"evolution of tourism ecosystem has important theoretical and practical value for promoting the coordinated and sustainable development of tourism economy and ecological environment in world natural heritage sites.Based on the paradigm of system science and axiomatic thinking,this study attempts to construct the connotation,characteristics and axiomatic definition of"spatial equilibrium"evolution of tourism ecosystem.Taking four world natural heritage sites in Guizhou as research samples,the evolution and influencing factors of"spatial equilibrium"of tourism ecosystem were analyzed by using system dynamics(SD)model,pressure-state-response(PSR)model,entropy weight method and geographical detector.The study found that:(1)The evolution of"spatial equilibrium"of tourism ecosystem refers to the ideal state in which the regional tourism ecosystem acts on the whole through its own positive and negative feedback when it is disturbed by local and affordable disturbances,and regulates and compensates through the system regulation mechanism,and finally forms a benign interaction between tourism development and regional nature,culture and human living environment.(2)The basic characteristics of"spatial equilibrium"of tourism ecosystem are relativity and dynamics,short-term"oscillation"and long-term"cycle".(3)Through the improved axiomatic definition of tourism ecosystem"spatial equilibrium"evolution,three evolutionary states of tourism ecosystem"spatial equilibrium"can be deduced,including equilibrium state,overload state and lag state.(4)From 2000 to 2020,the evolution and development of"spatial equilibrium"of tourism ecosystem in the four case areas showed different spatial and temporal evolution characteristics,regional differences and patterns.(5)The level of tourism pressure,the level of tourism economy,the state of tourism environment and the regulation of tourism policy are the common influencing factors of the evolution of"spatial equilibrium"of tourism ecosystem.Among them,the level of tourism economy is the primary factor in each case and year.The level of tourism pressure and the state of tourism environment have decreased their influence over time,and the influence of tourism policy regulation has gradually increased.
