Abstract: Wetland parks of Dianchi Lakeside have important ecological and landscape values. In order to obtain the public image perception of wetland park structure characteristics, and optimize the park image perception and service experience, six wetland parks of Dianchi Lakeside were selected as the research object, and tourist comments on tourism websites were used as the data source to obtain the public image perception of Dianchi Lake Wetland Park by content analysis, and an evaluation model of public image perception by IPA was constructed. The results showed that: (1) The public's comprehensive image perception of wetland parks included four aspects: natural resources and environment, human resources and environment, activity experience, and facilities and services. There were some differences in the perceived images of the six wetland parks, but the characteristics need to be further strengthened. (2) The overall high performance score of public image perception elements indicated that most public experience was good, while scenic spot maintenance and wetland water quality evaluation were relatively low and still need to be improved. (3) There were great differences in importance degree, among which the most important was the natural attribute of wetland parks, while the cultural attribute, such as background culture, was weak. Accordingly, some relevant suggestions were put forward for improving the construction management of wetland parks of Dianchi Lakeside.
