Abstract: In the response dynamic system of tourism urbanization,dynamic factors such as tourism resource endowment,economic development level,tourism demand and traffic accessibility promote the response of urbanization to the growth of tourism industry through causal feedback.Based on the relevant statistical data of Zhangjiajie from 2005 to 2018,a system simulation analysis model is constructed,the simulation interval being 2005-2030.The structure of the model system is divided into three subsystems,namely,population subsystem,economic subsystem and tourism subsystem.During the simulation period,each subsystem and its elements show a growth trend,but the growth rate and development trend are different.Under different scenario models,there are differences in economic level and the growth rate of tourism development.Through the comparison of the three scenario models,it is suggested that in order to promote the development of tourism,we need to strengthen infrastructure construction,increase tourism investment,and enhance tourism publicity at the same time.
