摘　　要：水库水温时空分布的变化对库区及下游河道环境及水生生态系统等产生重大影响,水库水温研究对库区及下游河道生态环境保护具有重要意义。回顾了国内外水库水温研究历程,介绍了主要的水库水温结构判别方法和水库水温研究方法,重点论述了水库水温机理性模型与智能算法模型的最新动态及前沿进展,总结归纳了水库水温分层特性、生态环境影响及其改善措施的最新研究成果,提出了未来重点研究方向:梯级水库影响下流域河-库系统水热传递规律、基于非静压的水库水流水温耦合计算、面向下游水温改善的水库分层取水生态调度。Changes in the spatial and temporal distribution of reservoir water temperature pose a significant impact on the environment and aquatic ecosystem in the reservoir area and its downstream rivers. We first made a review on the history of reservoir water temperature research in China and abroad, and introduced the methods of researching reservoir water temperature and discriminating the structure of reservoir water temperature. In particular, we expounded the latest developments and frontier progress of mechanism-based models and intelligent algorithm models for reservoir water temperature, and summarized the latest research findings in stratification characteristics and eco-environmental impacts of water temperature as well as improvement measures. Furthermore, we put forward some key research directions in future: the rules of water and heat transfer between reservoir and river, the flow-temperature coupling calculation based on non-static pressure, and the ecological scheduling of layered water withdrawal to improve downstream water temperature.
