In modern researches on the grain-size characteristics of lake sediments, the methods of incertical dividing sediments grain-size have no rigorous mathematical theory to support. To resolve this omission, the case of pollen zonation was taken for reference. 338 samples measured by Mastersizer 2000 from DG02 core of Gahai lake in Qaidam Basin were studied. Considering the clustering results of sequential clusters did not change the sequence of samples, tilia software package was used to divide the dividing sediments grain-size.
