Abstract Jiangsu Province has the longest inland restricted waterway among all the provinces in China. Ecological revetment is the hot topic of current research on the river or channel regulation engineering in China. Evaluation of ecological restoration capability of revetment is an important part of revetment design as well as an effective basis of the revetment selection. Liudaxian channel of Jiangsu province is chosen for this study, an index system and method for evaluating of ecological restoration capability of revetment is established. By analyzing the mechanism and process of revetment impact on river ecosystems, indicators of ecological restoration capability and quantitative calculation method are proposed in revetment structure level. Based on the degree of influence of the indicator to river ecological function, instead of expert opinion, the set value iteration method was used to analyze the degree of influence of the indicator to river ecosystem, which made weight assignments objectively. Combining with gray relational analysis (GRA) method, the set value iteration based on ecological theory - gray correlation evaluation model was established, which achieved quantitative evaluation of the ecological restoration of revetment. The evaluating result of the projects shows that revetment of wood pile with ladder-sand tube + three-dimensional vegetation net is chosen as the recommended slope protection measure. The revetment ecological restoration evaluation model proposed in this paper with the advantages of objective, standardized and quantitative, offers an effective and feasible tool for designers and managers to evaluate the ecological restoration capability of revetment.
