Based on statistical analysis on morphological data of nebkhas surveyed in the Hotan River Basin, Xinjiang, the changing regularity and characters of nebkhas＇ morphology in different development stages have been discussed. Results indicate that there exist better correlation among length, width and altitude of all kinds of nebkhas, but there are certain various shape characters in different nebkhas and the same type of nebkhas in differential development stages. On account of analysis on mathematical imitation of nebkhas＇ shape characters, regional ecological environmental and aeolian characters, the development of the nebkha can be divided into a growing stage, a stabilizing stage and a declining stage.
