Research Of System Dynamics Model Of The Complex System Of Tourism Small Towns Construction

The construction of small towns mainly for tourism is a very complex system problems which under the influence of economy, environment, tourism and other factors. In recent years, the development of tourist towns has shown some new characteristics: combined with self-conditions and pursuing the common development of regional. System thought help to better analyze and decide the direction of construction. By using the system dynamics, we can analyze the model and internal factors of the urban construction system. Taking Yanqing as the case, this paper comes to the trend of conclusion through the simulation of model from 2006 to 2025, the model includes four subsystems:economic, tourism, environment, and population. Through the simulation of the model and the adjustment of decision-making variables, this paper put forward four development modes: free development mode、 focus on the economic development mode、 focus on the environment development mode and coordinated development of economy-environment mode. According to the simulation results:the coordinated development of economy-environment mode is the most reasonable one through these four modes, in 2025, this mode’s attractions is:1386, GDP is 1.83 billion yuan, garbage disposal and sewage treatment rate respectively:98%and 85%. At the same time of control the number of attractions, improve the quality of the attractions and meet environmental protection requirements, GDP has maintained a rapid growth rate too. Finally, several development proposals are given by combined with simulation results, provide the reference for the government to specific the direction of development and policy.
