| 摘 要： | 以黄河下游影响带地下水系统为例,介绍了地下水系统的动力学特征分析方法,计算了其动力学特征指标:Hurst指数为0.91~0.97、Kolmogorov熵为0.054~0.081、最大Lyapunov指数均大于零、分维数为2.50~3.36。分析结果表明:黄河下游影响带地下水系统的各子系统都具有混沌性;Hurst指数刻划了系统的开放程度和受外界干扰程度;分形维描述了非线性系统的复杂程度。

| Abstract: | By the case of groundwater system of the affected zone along the lower Yellow River,the paper introduces dynamics characteristics analysis method of groundwater system,mean while,calculate its dynamic characteristics as follow: Hurst index is 0.91 to 0.97,for the Kolmogorov entropy 0.054 to 0.081,the largest Lyapunov index greater than zero,the fractal dimension of 2.50 to 3.36.The results proves that the chaos characteristic have participate in subsystems of groundwater system of the affected zone along th... |
