Some negative effects induced by river engineering are discussed, and the necessity of river ecological rehabilitation is demonstrated. From the viewpoint of river engineering, ecological rehabilitation means the restoration of channel configuration, riverbed profile, lost riparian vegetation, and wetland community. The following particular methods for ecological rehabilitation are presented: recovering the continuity of rivers and variety of water bodies, giving more space to rivers, and choosing river regulation schemes cautiously. Finally, some suggestions are made on the research of river ecological rehabilitation and its application based on some advances in corresponding research at home and abroad.
