With the rapid development of tourism industry in Jiuzhaigou since 1984, the scenic has experienced an increasing use of its natural and cultural environment for tourism, resulting in tourism resources being adversely impacted. Especially in peak travel period, the imbalance of tourists distribution in time and space leads to undesirable environmental and socioeconomic impacts. It is necessary to design a reasonable tourists shunt strategy with the objective of minimizing the environmental effects arising from tourism. Focusing on the goal, this paper proposes an evaluation model based on bottleneck theory and several shunt strategies. To evaluate the performance of the proposed strategies, combination of different shunt strategies is developed through simulation, and finds that the strategy integrating both static shunt and dynamic shunt strategy outperforms other strategies. The further research direction is proposed in the end.
