摘　　要：水库形成后,库区及水库下泄水较原河流状态下的水温发生一系列变化,进而会对鱼类资源产生影响。通过综合分析水温对鱼类分布、发育繁殖、摄食生长、行为习性的作用,针对水库形成后库区和坝下水温变化特点,初步探讨了水温变化对鱼类资源的影响,简单介绍了缓解水库下泄水水温变化措施的研究与实践,以期为缓解水库建设后水温变化对鱼类资源的影响提供参考。Reservoir formation leads to temperature change in reservoir water and reservoir discharge, which could affect fish resources. This study analyzes the ecological effect of water temperature on fish distribution, reproduction, feeding, growth and behavioral characteristics. Taking into consideration the characteristics of water temperature variation in reservoirs and its discharges, the paper discusses its impact on fish resources, and introduces the mitigation measures so as to provide technical reference Ibr relieving tile impact ol＇ reservoir construction on fish resources.
