Abstract: Shorelines of rivers and lakes are important components of river ecology.Currently, the special evaluation of shorelines is mainly focused on large rivers, and there are few evaluations of ecological shorelines for small and medium-sized rivers.To accurately carry out ecological shoreline restoration of small and medium-sized rivers, it is necessary to develop a targeted ecological shoreline evaluation system and methodology for small and medium-sized rivers.Based on the analysis of the current situation and existing problems of the shorelines of small and medium-sized rivers, we divide the ecological shorelines of small and medium-sized rivers into two categories: natural ecological shorelines and restored ecological shorelines.According to the principles of scientific comprehensiveness, quantification, and independence, evaluation indicators suitable for the ecological shorelines of small and medium-sized rivers are selected.Based on relevant technical specifications, the standards for various evaluation indicators have been determined, and a comprehensive evaluation method for the ecological shoreline of small and medium-sized rivers has been developed.The results showed that: ① According to the natural conditions of the natural ecological shoreline, we selected 20 indicators from four aspects, including natural structure, stability, ecological environment of the riverbank, and humanistic management, and constructed an evaluation index system.② For the restored ecological shoreline, in view of the post-restoration effect, we selected 23 indicators from four aspects, namely, structural status, ecological function, social function, and humanistic management, and an evaluation index system was constructed.③ The analytic hierarchy process was used to determine the weight of each indicator, and the ecological shoreline health index (ESHI) was used to calculate the ecological shoreline index of the whole small and medium-sized river, and the ecological shoreline health level was evaluated according to four grades: excellent, good, medium and poor.The research can provide a reference and standard for the management of small and medium-sized rivers and the ecological restoration projects of the shoreline.
