摘要
采用时间序列分析方法中一种重要的元参数估计法——R／S分析法，对桂林水文站2004~2005年的日观测水位、流量数据进行分析，得到298个Hurst指数估算值，进而对Hurst指数进行了分析，结果表明：漓江的水位、流量属于正偏随机游动，都具有较明显的时间记忆性，有一个25天左右的平均循环。
Rescaled range （R/S） analysis, an important parameter-free estimation of time series analysis method, was applied to analyze the observation data of daily water level and flow of Gulling hydrometric station from the year 2004 to 2005, which contributed 298 Hurst exponents as results. The results of the analysis of the 298 Hurst exponents demonstrated that the water levels and flow of Lijiang river both are positive skew random walking, have relatively obvious time memory and have a mean circulation of 25 days approximately.
