| 摘 要： | 针对珠江河口地区水流受洪水波、潮波共同影响水位变化的复杂问题,为研究其演变特性,以南沙站、三沙口站和万顷沙西站为例,基于历史实测月高潮位数据,重构潮位时间序列相空间,采用自相关系数法求得3个潮位站月高潮位序列的延迟时间,并分别利用G-P算法和主分量分析法分析该序列混沌特性,求得其饱和关联维数。结果表明,月高潮位时间序列具有明显的混沌特性。

| Abstract: | The evolution characteristics of the tide level in estuary districts are complicated because of the combined effect of floods and tidal waves.Based on the reconstruction theory of the state space,the auto-correlation function,the G-P algorithm and the principal component analysis are used to study the chaotic characteristics of the monthly high-tide-level series of Nansha,Sanshakou,and Wanqingshaxi stations in Pearl River Delta.Using the methods,the delay time and the saturated correlation dimension are eva... |
