摘　　要：大中型水电水利工程建设引起的低温水下泄问题是主要的生态问题之一。目前水库水温计算有经验公式法和数学模型法两大类。指数函数法和余弦函数法是目前水库水温计算两种常用的经验公式方法,也是现有规范推荐的方法。选取了我国11个不同类型的代表性水库,利用实测资料分析研究了两种方法在计算水库水温精度的差异。通过比较研究,笔者建议在有较好的类比水库资料时采用指数函数法,否则建议采用余弦函数法。Low Temperature water discharging problems caused by the construction of large and medium scale hydropower and water conservancy project is one of the major ecological problems. Nowadays, there are two categories method to calculate the water temperature including experienced formula method and mathematical model. The most experienced two methods we had now is Exponential function Method and Cosine Function Method for calculating the water temperature, and they also are the most for- mal and recommended method. This research project selected 11 representative reservoirs in China, and used actual measuring data of these 11 reservoirs to analysis and research the precision of these two methods and different characteristics. According to our research, we found that we could use Exponential function Method if we have useful and integrated date and information of reservoir, otherwise, we suggest apply Cosine Function Method.
