Abstract: The healthy and sustainable development of rural tourism is affected by various factors. By constructing the system dynamics model of the coordinated development of rural tourism, the paper analyzes the feedback relationship and interaction mechanism among various elements of the economic subsystem, ecological subsystem and social and cultural subsystem, then identifies the driving mechanism of coordinated development of rural tourism. Rural tourism coordinated development pattern can be divided into five kinds of model, such as resources and environment dependent （N model）, industry oriented （E model）, ecological environment protection （R model）, the social and cultural balance （S model） and the economy, ecology and society coordinated development （ERS model）. The simulation results show that ERS model is the coordinated development of rural tourism system optimal model. Furthermore, some suggestions are put forward, such as giving full play to industrial multiplier effect, improving environmental governance ability, improving community participation awareness and ability, and improving rural tourism policy response system.
