Abstract:To clarify the integrity of river ecosystems, identify the main indicators affecting the degradation of the river ecological integrity, and select scientific, reasonable, and feasible indicators for its quantitative characterization, this study employs bibliometric methods to outline the broad connotations of river ecosystem integrity both domestically and internationally, concretizing river ecological integrity into hydrological process integrity, habitat process integrity, and biological process integrity. The research progress and application of river ecological integrity assessment were summarized systematically, the usage of various indicators was analyzed, and problems in the selection of indicators and reference state for the current river ecological integrity assessments were identified. An assessment framework was constructed by applying the ecological integrity theory to small hydropower-developed rivers as an example, and the challenges and future trends in river ecological integrity research were discussed.
