黄河径流长期演化模式与EMD灰色自记忆模型
Evolution modes and EMD gray self-memory model of the Yellow River water resources
摘要
Abstract
To better understand the evolution modes and self-memory characteristics of the Yellow River annual runoff,a gray self-memory prediction model is developed by using empirical mode decomposition theory.A auto-correlation function is adopted to define the backdate orders of this model to improve its accuracy.The results show that the runoff series at Huayuankou gauge can be decomposed into seven intrinsic mode functions（IMF） and a tendency function.Since 1965 the evolution modes and periodicity of runoff series has changed under the influences by water resources development and climate change in this river basin.关键词
