摘要:
将灰色系统建模方法和自记忆建模结合起来,提出了年径流预测的灰色自记忆模型。实例研究表明,灰色自记忆模型能很好地反映动态数据序列的极值趋势,且具有较满意的拟合及预报精度。

Predicting annual runoff with grey self-memory model
Abstract:
The grey self-memory model for annual runoff was established on grey system and self-memory theory.Examples show that the suggested model can reflect the extreme trend of recorded annual runoff dynamic variation with satisfactory simulation and predicting precision.
Key words:  annual runoff  grey forcasting  self-memory model
