Abstract: This article discussed and summarized a broad range of key issues prevailing in wetland restoration both from the ecological and socio-economic perspectives, with emphasis on the definitions, restoration modes, assessment and application of eco-hydraulics in wetland restoration, as well as the socio-economic mechanism for wetland restoration. The article argued that the narrow & broad concepts of wetland restoration were both valuable and meaningful corresponding to the different circumstances, their application should be quite site-specific. In practice of wetland restoration, the first step should be priority assessment of the necessity and feasibility of the candidate sites to be restored, and then prudent selection of the positive or passive modes & measures of restoration project based on the assessment of wetland degradation. With regard to the complication and uncertainty lying in the wetland restoration project, it is vital to pre-and post-assess the restoration project by using a more comprehensive measurement and index system. As the state-of-art issues, the article prospected the application of modern eco-hydraulic engineering in wetland restoration, and socio-economic mechanisms of community-based participation and market-oriental incentives were also targeted. Finally, the article concluded that the longitudinal, lateral and vertical hydrological connectivity with upstream subcatchments, adjacent watershed and groundwater system should be addressed in wetland restoration project, and the ecological integrity and health of the larger scale watershed should be maintained to guarantee the long-term persistence of restored wetland.
