Yuntai Mountain is Chinese famous tourist spot. The study on the ecological security of Yantai Mountain has more practical significance. This paper studies on the Yuntai Mountain and the author constructs an ecological safety (eco-safety) evaluation index system characterized by Yuntai Mountain scenic eco-environment system and constructs the Yuntai Mountain index system on the basis of P-S-R model. From the overall evaluation results, the eco-safety is relatively high in Yuntai Mountain area according to the eco-safety value 0.8577, which is between 0.75 and 1 safe state value.
