| 摘 要： | 本文通过对乌鲁木齐河年最大洪峰流量实测资料与历史洪水资料的分析，选定了正态分布，对数正态分布，三参数对数正态分布，Ｇｕｍｂｅｌ分布，Ｐｅａｒｓｏｎ－Ⅲ型分布和对数Ｐｅａｒｓｏｎ－Ⅲ型分布等６种线型，利用极大似然法对各种分布函数的参数进行了最优估计。

| Abstract: | Flood frequency analysis has been proved to be complicated in terms of its distribution function option, corrisponding parameter estimation and available information used- The author makes use of the normal, lognormal t three-paramter lognormal, Pearson type 3,log-Pearson type 3 and Gumbel distributions with the maximum likelihood method and combining the systematic record of flood discharge with historical flood data to define the best fitted distribution of annual largest peak discharge in Urumqi River. At last logPearson type 3 proved to be as the best fitted distribution in the consistence of annual peak discharge in Urumqi River as a result of the visua1 assessment of the plot of abserved values the fitted quanti1es and Filliben probability-plot correlation test. |
