Considering the importance of social stability risk evaluation for major water conservancy projects (MWCPs), this paper creates a feasible evaluation index system for such projects in fragile ecoenvironment regions (FEER) through literature review, questionnaire surveys and data analysis. Then, a risk evaluation model was construction based on the set pair analysis (SPA) and the principal component analysis (PCA). The proposed model was applied to a MWCP in Shaanxi Province, China, revealing that the project has a low level of social stability risk. The evaluation result agrees with the actual situation, confirming the reliability and rationality of the proposed model. On this basis, several suggestions were proposed to further mitigate the social stability risks of the MWCPs in the FEER. The research findings provide a valuable reference for similar projects in FEER.
