摘要
当今在人类的不断活动和水文气象因素的双重影响下,径流序列呈现出的更为复杂的非线性和分形的特征。文章将滑动移除数据技术和重标方差法相结合,有限元建模计算研究河川径流时间序列突变的规律,反映出在不同阶段时期上的河流分形特征,有效诊断在变化环境下的径流时间序列非线性和分形特征。
Affected by the human activities and hydro-meteorological factors,the runoff series are characterized as more complicated non-liner and fractal. Combined with the sliding removal data technology and rescaled variance method,this paper researched and calculated the law of runoff time series mutation by establishing finite element model to reflect the characters of river fractals at different stages,can diagnose the nonlinear and fractal characters of runoff time series under changing environment effectively.
