| Abstract: | Based on the change-point theory and methods,the likelihood ratio method testing in the mean and the Schwarz Information Criterion testing in the variance,change points of time series of the river runoff such as the full year runoff,the flood season runoff,the dry season runoff,and the least monthly runoff were recognized for main gauge stations of Guangdong Province from 1956 to 1999.Spatial-temporal location of these tested change points were described in detail,key features of the characteristics variabi... |
