摘要：To solve the ecological deterioration problems of the medium and small reservoirs' downstream areas caused by water interception, the ecological restoration technique for dam's downstream area is studied in this paper. Based on the investigation and analysis of the current ecological environment of a medium and small reservoirs' downstream area in Qingyuan county of Liaoning, the downstream minimum ecological flow, with which the ecological environment of downstream can connect to that of upstream, is calculated. In the way of drawing water above the dam and building underground dam, the minimum ecological flow for the ecological environment of the downstream area will be able to reach a level where the continuity of the ecological environment is maintained. Consequently the aquatic habitats and stream ecological environment of the dam's downstream channel can be improved and recovered.
