Abstract

After applying geostatistical analysis to the mean size, sorting and skewness for the sediment samples collected from the eastern Beibu Gulf, the AA. compared the semivariograms of these 3 parameters by using different interpolation distance. The results indicated that the range for sorting coefficient was physically meaningful. The trend vectors calculated from grain size trend analysis model were consistent with the annual ocean circulation patterns and sediment transport rates according to previous studies. Therefore the range derived from the semivariogram of mean size can be used as the characteristic distance in the grain size trend analysis, which may remove the bias caused by the traditional way of basing on experiences or testing methods to get the characteristic distance
