With the rapid development of wetland tourism,the negative impact of tourism activities on the wetland ecosystem is becoming increasingly prominent.Coastal wetland ecosystem is a complex and fragile ecosystem.It is significant to explore the impact of tourism on the coastal wetland ecosystem and evaluate the ecological safety of coastal wetland tourism.Based on P-S-R model,this paper constructs an evaluation index system in terms of pressure,state and response,and uses ecological safety evaluation method to evaluate the coastal wetland tourism ecological safety of Yellow River delta wetland,Long Island wetland and Jiaozhou bay wetland,which are the representative of coastal wetland of Shandong Province.The results show that Yellow River delta wetland and Long Island wetland are in safe state while Jiaozhou bay wetland is in a relatively safe state.According to the evaluation results and the present situation of coastal wetland tourism development in Shandong Province,the paper analyzes the influential factors in the coastal wetland ecological safety,and then proposes some countermeasures for the development of coastal wetland tourism.
