摘　　要：高坝泄洪会导致下游水体总溶解气体过饱和,鱼类长期处于这种环境容易患气泡病甚至死亡。为保护生态环境,找出切实可行的TDG饱和度消减措施,我国针对高坝泄洪导致的总溶解气体过饱和现象开展了大量研究。对高坝工程过饱和溶解气体的产生、释放过程、鱼类对过饱和溶解气体耐受性、TDG饱和度预测模型及TDG过饱和减缓措施的研究成果进行了总结,同时针对已有研究成果的不足提出了建议,旨在为进一步开展研究工作提供参考。Supersaturated total dissolved gas caused by high dam flood discharge would lead fishes to suffer gas bubble disease. In order to lower the saturation of total dissolved gas and protect the aquatic environment,studies were made in the past decades through prototype measurements and laboratory experiments. This paper summaries the cause and dissipation process of supersaturated dissolved gas,avoidance response of fishes,TDG prediction model and mitigation measures and other respects of high dam projects. Suggestions for future work were proposed.
