[Objective] The objective of this study is to comprehensively assess the ecological revetment of urban river course in order to provide the theoretical basis for urban river construction.[Methods] Considering revetment safety, ecological environment, landscape suitability and socioeconomic benefits, we established an index system of comprehensive assessment on the ecological revetment of urban river course by using fuzzy analytic hierarchy process-principal component analysis(FAHP-PCA).[Results] The ecological brick slope was the optimal measure in Hefei City as it showed the highest assessment value of 1.57, which was higher than that of ecological concrete slope(-2.39) or erect retaining wall(0.82). The main factors that influenced the quality of ecological revetment included structural stability, biodiversity, water environmental remediation, hydrophilicity and public recognition. The result was consistent with the assessment result from FAHP and PCA.[Conclusion] Based on the excellent applicability and rationality, it is convenient to determine the main factors that affecting ecological revetment, therefore, FAHP-PCA can be used in the comprehensive assessment on ecological revetment of urban river course.
