| 摘 要： | 根据全国１６０座大中型水库的实际观测资料，对坝前年最高水位的变化特性进行了较系统的分析研究。结果表明：年最高水位为独立随机变量，概率分布多为负偏，可由三参数对数正态表征。参数由概率权重矩法估计。

| Abstract: | This paper studies and analyses the statistical properties of the national 160 reservoirs with large and middle size.The results show that maximum annual water levels of reservoir can be considered as independent variables and described by log-normal distribution.The probabilistic distribution of maximum annual water levels mostly have characteristic of negative skewness.Three parameters of log-normal distribution can be reasonably estimated using probability weighted moment method. |

| Keywords: | maximum annual water level of reservoir log-normal distribution probability weighted moment |
