In- situ cosmogenic nuclides dating is a newly developed method, which is used for age of geomorphological surface and earth surface processing. Due to its unique advantages, the method has been received worldwide recognition and application. Using to geological dating is refined in native. Since most domestic researchers lack a deep understanding of the age calculating model. Four calculating models are described, which have been widely accepted by foreign researchers. In order to using suitable model get reliable ages by those, who are beginners and the researchers that attempt to apply the in- situ cosmogenic nuclides dating. The difference of these models were compared and analysed. The unique advantages and application fields of each model are evaluated.
