Abstract: Cultural heritage sites are linked to tourists by docents’ interpretation,which can enhance the cultural experience of tourists,activate,inherit and innovate the value of the cultural heritage sites,reconstruct their functions,and realize their values as well.This paper made a case study of the Palace Museum’s interpretation service from tourists’ perspective by making a LSTM-IPA analysis with a sample T test and a IPA factor analysis based on a comparison of the importance and satisfaction degree of multi-dimensional perception.The results are：（1） There are some differences in tourists’ perception of the evaluation indexes of interpretation service quality in the Palace Museum;（2） Tourists are least satisfied with Palace Museum’s route design and the docents’ interpretation skills; （3） Services for improvements include a more vigorous and interesting way of interpretation,a better designed route of tour and more patient responses to tourists’ inquires.These results make it clear that tourists’ experience and satisfaction are closely related to docents’ interpretation service.Based on the findings,this paper offered some practicable approaches and strategies for promoting the service level and skills of the docents for the reference of other cultural heritage sites.
