| 摘 要： | 采用PPCC检验法对金清水系湖漫水库坝前年最高水位常用的几种分布线型进行对比分析。除了正态分布、二参数对数正态分布和耿贝尔分布的参数估计用矩法估计外，其他三种分布的参数估计统一用基于绝对值准则的适线法。分析结果表明实测值和理论值的拟合效果耿贝尔分布最差，P-Ⅲ型分布和LP-Ⅲ型分布较好，三参数对数正态分布最好，建议把三参数对数正态分布作为岳城水库坝前年最高水位的分布线型。 |
| 关 键 词： | 湖漫水库 PPCC检验法 坝前年最高水位 三参数对数正态分布 |

| Abstract: | Taking Human Reservoir of Jinqing water system as an example, PPCC testing is applied to compare several common distributions of the maximum annual water level of the reservoir, including normal distribution, two parameter lognormal distribution, Pearson Type Ⅲ distribution （P-Ⅲ）, lognormal Pearson Type Ⅲ distribution （LP-Ⅲ）, three parameter lognormal distribution and Gumbel distribution. Moment method is used to estimate the parameters of the three former distributions and curve-fitting method is applied to the others. The results shows that three parameter lognormal distribution fits best and Gumbel distribution fits worst while P-Ⅲ and LP-Ⅲ are superior to the rest distributions. Therefore, three parameter lognormal distribution is proposed to describe the maximum annual water level of Human Reservoir. |
