Combined with the development status of water conservancy scenic spots, this paper uses the analytic hierarchy process and the comprehensive index evaluation method to construct a comprehensive index evaluation index system for the high-quality development of water conservancy tourism industry’s integration, including 3 first-level indicators such as sense of security, sense of gain and happiness, and 16 second-level indicators such as engineering safety, ecological security and tourism safety. Taking 10 national water conservancy scenic spots in Zhejiang Province as an example, the secondary indicators were assigned through data collection, data analysis, and expert scoring. The results showed that the comprehensive index of high-quality development of water conservancy tourism industry’s integration in all national water conservancy scenic spots was excellent, and the scores of the first-level indicators of sense of security, sense of gain and sense of happiness decreased layer by layer, indicating that the difficulty of accessibility increased layer by layer, which was in line with the general law of accessibility of sense of security, sense of gain and sense of happiness. The feasibility of the comprehensive index evaluation index system for the high-quality development of water conservancy tourism industry’s integration was verified.
