Study Of System Dynamics On Environmental Capacity Of The World Heritage Tourism

Tourism carrying capacity is an important measure whether tourism environment is consistent with its development. With the development of mass tourism, there is a lot of overloading situation in the scenic area。The negative impact of tourism activity on the environment is more and more obvious, that has seriously affected the quality of tourism products and long-term development of scenic spots. Based on research progress on tourism carrying capacity home and abroad, this article summarizes and analyzes the definition, theoretical basis and application. System Dynamic method is produced as a new exploration. Take Summer Palace as an example. It is a complex, open system. First, carry out a qualitative analysis of structure of its resources and the environmental capacity quo. Then using the correlation coefficient analysis, analysis the relationship between satisfaction and crowding. On this basis, with the application of the principle of control theory, causal feedback system has been analysis, a system simulation dynamics model of Summer Palace has been set up. Through the model establishment, model operation, model checking and so on to find the law of tourism environment capacity of Summer Palace. The results show that: in Summer Palace, overloading exists in specific time and regional. Tourists'stay time is a very important factor affected the space capacity of the Summer Palace. In addition to, the flow rate between saturated zone and unsaturated zone also affects the quantity of tourists within the region. In this study, the impacts of stay time and diversion measures on the environment capacity of Summer Palace are simulated. Based on this, a number of management measures on heritage tourism environment capacity have been produced in hope to give some inspiration of the capacity management.
