Dynamic Simulation of Regional Ecological Security of Tourism

Ecological security is the basis for sustainable development of regional tourism.Environmental problems caused by tourism development have threatened the security of ecosystem,while unsafe ecosystem will affect sustainable development of tourism as well.A system dynamics model,which can describe the causal feedback relationships of regional tourist ecological security system,was built by using system dynamics.On basis of system dynamics modeling and simulation,the different modes of tourism development are put forward through regulation and control of several key indexes.Results show that environmental protection,tourism investment,policies,regulations and tourism staff quality are the main influencing factors of ecological security of tourism in Liaoning Province.
