It is found that the distributions of flood forecasting errors both in humid or semi-humid region approximately obey the law of normal distribution and the method based on POME is effective for calculating the distribution of flood forecasting errors.

结果表明，我国湿润和半湿润地区的洪水预报误差近似服从正态分布，且采用阳ME方法计算洪水预报误差分布是可行的。
