    Abstract:

    [Objective] To comprehensively evaluate the ecological revetments of rural river,in order to improve the comprehensive level of ecological management of rural rivers in the construction of new countryside.[Methods] Comprehensive evaluation systems of ecological rural river revetments in plains, hills and mountain areas were built from five aspects, namely:cost, construction materials, effects on the function of water conservancy, ecological function and social landscape features. Index weights of ecological rural river revetments in the three areas above mentioned were calculated using analytic hierarchy process and the ecological revetments were evaluated using rank-sum ratio.[Results] Seven kinds of ecological revetments, including ecological stone cage revetment, ecological concrete revetment, plant revetment, timber revetment, rock revetment, ecological brick retaining wall and ecological bag revetment, were chosen to be comprehensively evaluated in three kinds of rural rivers. It was concluded that the ecological rick retaining wall and the plant revetment are suitable for the middle and lower reaches of Shiwuli River, their indexes of WRSR are 0.692 3 and 0.662 2; the ecological brick retaining wall and the ecological concrete revetment are suitable for the Caishi section of Cihu River, their indexes of WRSR are 0.663 5 and 0.659 0; and the ecological concrete revetment and the ecological stone cage revetment are suitable for the upstream of Jiuhua River, their indexes of WRSR are 0.551 6 and 0.537 8.[Conclusion] The result of this evaluation system is reasonable and can be used to improve the construction level of ecological revetments of rural river.
