降水数据的插补可有效地改善数据系列的完整性。以西柳沟流域作为毛不拉孔兑的参证流域，采用EDM和BP算法对毛不拉孔兑缺失的降水量进行插补，并与已有的相关分析法、频率分析法及逐步回归分析法进行了比较。研究结果表明：EDM－BP模型综合利用了西柳沟降水序列EMD分量的有效信息，因而能较好地反映降水量的变化趋势，在数据拟合和预测方面达到较高的精度，适合毛不拉孔兑降水数据的插补，在其它水文数据插补延长中具有一定的推广应用价值。

The interpolation of precipitation data can improve the integrity of data series effectively .Tak-ing Xiliugou River basin as reference , the paper interpolated the missing precipitation data in Maobula-kongtuo interpolated with Empirical Mode Decomposition (EMD) and Back Propagation algorithm (BP) methods.The results were compared with that of correlation analysis , frequency analysis and stepwise re-gression analysis .The results show that EDM -BP model takes full advantage of effective information of Xiliugou the interpolation of precipitation data in EDM decomposition series , therefore which can better reflect the trend of precipitation series .Its precise of data fit and forecast is higher and is suit to the inter-polation of precipitation data at Maobulakongtuo .The result has certain application value to the interpola-tion and extrapolation of other hydrological data .
