Tourism Environment Based On System Dynamics Research On Bearing Capacity And Countermeasures

With the rapid development of tourism,the economic income and employment posts of tourist destinations have increased significantly.At the same time,the rapid development of tourism and the overexploitation of scenic spots have brought about air pollution,water pollution,forest coverage and so on,which seriously damaged the natural ecological environment of tourist sites,and the environmental pollution of tourist sites has become a concern at home and abroad.The focus.Therefore,through a scientific and reasonable method to quantify the current situation of tourism environmental capacity,to determine the reasonable tourist density and scenic area,and to keep the environmental capacity of the tourist environment within the scope of environmental bearing capacity of the scenic area,it is of great significance for the development of Mount Lu scenic spots to plan and guide the development of tourism.This paper takes Mount Lu scenic spot as the research object.Firstly,it expounds the research results of the domestic and foreign tourism environmental carrying capacity and the application of the system dynamics method,and defines the related concepts of tourism ecological security and tourism environmental carrying capacity,and describes the theoretical knowledge system related to the thesis research.On the basis of previous research,the paper divides the tourism environment system into tourist economy subsystem,space resource subsystem,population subsystem and environmental pollution subsystem.It selects the evaluation indexes of the carrying capacity of each subsystem,and constructs the feedback flow of the tourist environment carrying capacity system through the analysis of the internal variables and the relations among the systems.According to the relationship between the variables,the simulation equation is constructed,the pollution control ability,the number of tourists and the tourist area control parameters are simulated.The paper has made some progress in the following two aspects:(1)Through the analysis of the relationship between the internal elements and the system between the subsystems of the tourist environment system of Mount Lu scenic spot,the feedback flow chart of the environmental bearing capacity of the tourist environment is drawn,and the basic model of the sewage flow rate,the basic model of the tourist quantity flow rate,the basic tree model of the resident populationflow rate,is constructed.The basic tree entry model of the scenic area,the basic rate of flow for residential and service facilities,and the basic tree entry model.(2)The application of the model to simulate the lushan scenic area of the current strategy under the dynamic change of tourism environmental bearing capacity,the lushan scenic area environmental bearing capacity of the status quo,and the change trend of future years the result of simulation shows that the lushan scenic area need to increase in pollution control ability,in the number of tourists in the existing planning tourist growth strategy will be out of tourism environmental bearing capacity,tour of the scenic area can reduce the question countermeasure simulation,the results show that improving the capacity of pollution control,limit the number of tourists measures,increase scenic area as far as possible,and help to lushan scenic area tourism sustainable development.
