    摘要:

    [目的]探讨乡村河道生态护坡的评价方法,为提高新农村建设中乡村河道生态综合治理水平提供支持。[方法]从生态护坡成本、施工材料、对基本水利功能影响、生态功能和社会景观功能等5个方面系统地构建平原、丘陵和山区3种乡村河道生态护坡综合评价体系,利用层次分析法确定这3种乡村河道生态护坡指标权重,并运用秩和比法对生态护坡进行评价。[结果]对生态石笼护坡、生态混凝土护坡、植物护坡、木桩护坡、山石护坡、生态砖挡墙和生态袋护坡等7种生态护坡进行选择并在3种不同乡村河道下进行综合评价,确定出生态砖挡墙和植物护坡适用于十五里河中下游河段,其加权秩和比值(WRSR)值分别为0.692 3和0.662 2;生态砖挡墙和生态混凝土护坡适用于慈湖河采石段,其WRSR值分别为0.663 5和0.659 0;生态混凝土护坡和生态石笼护坡适用于九华河上游段,其WRSR分别为0.551 6和0.537 8。[结论]该评价体系的评价结果较为合理,可用于改善和提高乡村河道生态护坡的建设水平。

    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.
