Research On The Evolution Of Urban Tourism Environmental System Resilience And Its Dynamic Mechanism

The rapid development of the urban economy and the growth of residents' net income have increased the demand for tourism and leisure,which not only stimulated the vigorous development of the tertiary industry such as tourism,but also brought greater impact and pressure on the urban tourism environment system,such as urban water bodies.The leisure environment is damaged or even deteriorated.Excessive urban tourism development and tourists inflows increase the vulnerability of the urban tourism environment system.The contradiction between the development of tourism economy and the ecological environment is becoming increasingly acute.How to reduce the vulnerability of the tourism environment system and improve the anti-interference and restoration capabilities of the urban tourism environment system while developing the urban tourism economy and pursuing the rationalization of tourism economic,social and ecological benefits has become a hot topic of research.The development and development of the theory of resilience and the theory of social ecosystems provide a theoretical analysis framework for the research on the resilience of the urban tourism environment system.Therefore,this article takes 14 cities in Gansu Province as examples to study the evolution of the resilience of the city's tourism environment system and its driving mechanism.This paper constructs a comprehensive evaluation index system for the resilience of the three subsystems of the social,economic,and ecological environments in the urban tourism environment system,establishes the entropy-TOPSIS resilience evaluation model,and quantitatively measures the resilience of the urban tourism environment system.Using Arc GIS analyzes the spatial autocorrelation of the resilience of the tourism environment system in different urban areas,explores the spatial-temporal changes and spatial correlations of the resilience of the city's tourism environment system,and performs standard deviation ellipse and center of gravity trajectory analysis on the resilience of the city's tourism environment system.Finally,it uses system dynamics to construct causality diagrams and stock flow diagrams of various elements of the urban tourism environment system,clarify the dynamic mechanism that promotes the evolution of the resilience of the urban tourism environment system,and simulate the established resilience model of the urban tourism environment system.The main conclusions of this article are as follows.The overall level of the resilience of the tourism environment system in cities in Gansu Province has shown an overall upward trend.The resilience of the city's tourism environment system has continued to increase but the overall level is still low.The urban tourism economicdevelopment has increased the pressure on the ecological environment.The resilience of the system has the spatial distribution characteristics of "high in the middle,high in the northwest,and low in the southeast." The urban tourism environment system's resilience spatially aggregates and disperses,coexist in global autocorrelation.The center of gravity of the resilience shifts to the northwest as a whole.System dynamics simulations show that the resilience of the tourism environment system in most cities in Gansu Province will keep fluctuate rise in the future.The sustainable development model can improve the resilience of the city's tourism environment system.
