Abstract：Ecological recovery of rivers and lakes is essential for promoting high-quality development in water conservancy and advancing the Beautiful China initiative. Based on an of analysis of the trends in river and lake ecological evolution and the theoretical advancements in ecological recovery,this study proposes a framework for stepwise ecological restoration and a technical system for river and lake recovery. The stepwise ecological restoration theory fully considers the historical degradation and current conditions of watershed ecosystems,advocating for an incremental,phased,and location-specific approach to environmental management,ecological restoration,and natural recovery. This approach is characterized by four main features of "tailored solutions,goal orientation,systematic governance,and continuous monitoring",to progressively restore degraded ecosystems. Guided by the stepwise ecological restoration theory,key environmental restoration technologies have been developed,including "dynamic water replenishment-vegetative bank protection-in-situ algae removal" and indigenous microorganism-based ecological restoration methods. These techniques provide theoretical and technical support for the ecological recovery of rivers such as the Yongding River and the Maozhou River.
