| 摘 要： | 分析了遥测降雨观测资料的分布特征，引入抗差估计理论修正遥测降雨资料中出现的异常值，提高实时洪水预报精度。根据实际应用中出现的问题进行了改进。对闽江七里街流域1988～1998年45场洪水的暴雨资料，用生成的误差系列比较了各种方法的修正效果和探测效率。改进后的三步抗差修正的优越性获得了较好的修正效果．均超过60％。

| Abstract: | Robust estimationtheory was taken to correct outliersin the remote system on the basis of analyzingthe rainfall distribution characteristics.The three-sfepwise improvementwas made to solve physical problems.Rainfall data of 45 floods during 1988-1998 in Qilijie Basin was used to compare correction results and detection efficiency of different methods.The results showed the improved three-stepwise robust correction method was a better method for correctionof rainfall observation error. |
