摘要

[目的] 探讨城市河道生态护坡综合评价方法，为城市河道建设提供理论依据。[方法] 从护坡安全性、生态环境性、景观适宜性和社会经济效益4个方面构建城市河道生态护坡综合评价指标体系，采用模糊层次-主成分分析综合评价方法。[结果] 合肥市四里河、南淝河和十五里河3种生态护坡综合评价值分别为：多孔生态砖护坡1.57，生态混凝土护坡-2.39，生态砌块直立挡墙为0.82，多孔生态砖护坡评价结果较好。影响生态护坡综合评价的主要因素有结构稳定性、生物多样性、水环境修复、亲水性和公众认可度；评价结果与模糊层次分析法及主成分分析法评价结果一致。[结论] 模糊层次-主成分分析法具有较好的适用性和合理性，易于确定影响生态护坡的主要因素，可作为城市河道生态护坡综合评价方法。

Abstract

[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.
