摘要
为同时考虑水文要素年际变化和年内变化的统计规律,可利用已经出现的实侧数值所提供的信息对原有预测结果进行一定的修正。本文把时间序列分析与随机函数典型分解方法相耦合,对黄河上游龙羊峡水库融雪期迳流预报作了尝试,效果良好。
For the sake of concerning both yearly and monthly variation of hydrological elementsso that we can use information of real-time data to reform the forecasting values which werepredicated before, this paper couples up the threshold autoregression model and the typicaldecomposion of random function model to give a predication for longyangxia reservoir in theupper reaches of yellow river. The results is excellent.
