Comprehensive Evaluation Methods of Rural River Ecological Revetments
[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.
