Abstract : *(250~1000 words)

Green ecological treatment of waterway bank slope is an important part of river ecological treatment. The ecological treatment for soil bank slopes of inland waterway cannot mechanically apply to the current riverway ecological revetment techniques, and instead, it still needs in-depth study on the mechanism of bank slope buckling failure and take ship navigation into consideration, as well as carry out systematic studies and engineering tests by combining the key bank slope ecological treatment techniques used in green vegetation measures. It is necessary to carry out the research on the evaluation theory of the ecological treatment of the bank slope in order to effectively guide the standardized construction of the green ecological bank protection and implement the goal planning and post-engineering evaluation of the green ecological treatment of the bank slope. This paper proposes the basic principles and main contents related to green ecological bank slope design, and constructs the evaluation index system for the green ecological bank slope treatment scheme and establishes the multi-level fuzzy comprehensive evaluation model. Bank slope design proposed in this paper focuses two parts: Determination of longitudinal river partitions, and determination of transverse riverway partitions. This model has been smoothly applied to the comprehensive evaluation of the ecological bank protection pilot project of the waterway in Naji reservoir area in Guangxi, China.The research results can be used to guide the planning of the green ecological slope protection project scheme, the project implementation and the acceptance evaluation.
