Abstract：Based on three decades’ research and practical experiences in lake eutrophication control field, the overall idea with pollution source systematic treatment, restoration of watershed aquatic runoff generation mechanism, improvement of lakes habitat and enforcing management as the main direction on the lake eutrophication control was put forward with special focus on the concept and restoration tactic about restoration of watershed clean water runoff generation mechanism. The concept of watershed clean water runoff generation mechanism was introduced with an analysis on the runoff generation, concentration and inflow processes in the watershed runoff. The concept, idea, technical methods of the clean water runoff generation mechanism restoration and key problems during the restoration were discussed based on the explanation of the causes of destruction. Taking the Dongda River Watershed of Fuxian Lake as an example, the river watershed was divided into three regions, that is, clean water runoff generation region, pollution control and purification region and lakeshore region. The clean water amount and pollutants generated were analyzed in the three regions and the relevant restoration countermeasures were suggested based on investigation of regional characteristics.
