| Abstract: |
| By using the method of R/S analysis of fractional Brownian motion and the formula of information dimension, the fractal characteristics of time series of mean monthly sea level along the coast of Guangxi is analyzed. The dynamic process of the mean monthly sea level has the characteristics of persistence. Hurst indexes range from 0.54 to 0.86, box dimensions, DB, from 1.14 to 1.46, and information dimensions,DI, from 0.86 to 0.90. |
| Key words: mean monthly sea level fractional Brownian motion R/S analysis fractal dimension |
