摘要
水库水温分层及其低温下泄水造成的"冷害"是水电工程建设生态环境影响的重点关注问题之一,水库水温研究对于库区的生态环境保护具有重要的现实意义。以水库水温模拟研究为线索,介绍了主要的水库水温结构判别方法和水库水温计算方法,回顾了国内外水温模型与软件的发展,重点分析了水库水温的生态环境影响及其缓解措施。最后,总结了我国水库水温研究的现状及存在问题,并提出了今后的发展趋势。
Water temperature stratification within reservoirs underflows and the ＂chilling injury＂ caused by the dis charged low-temperature water flows pose one of the primary concerns for both eco-environmental conservation and hydropower operation. It is therefore, study on impacts on eco-environmental from reservoirs underflows temperatures appear to be practically useful. The paper begins with simulation study of reservoir water temperature , reviews the development in water temperature models and software in home and abroad, then examines the primary approaches for structural discrimination and calculation of reservoir water temperature. Emphasis are placed on ecoenvironmental impacts from reservoir water temperature as well as the mitigation measures. Furthermore, the status quo, exiting problems in China are examined. Finally, the paper concludes with suggestions for future reservoir water temperature study.
