Objective       To investigate the application of cognitive emotion regulation strategies and coping style in military college students with different trait anxiety

and the relationship between them and anxiety. Methods       A cluster sampling survey was conducted among 328 military college students by using the statetrait anxiety inventory（STAI-Formy），cognitive emotion regulation questionnaire（CERQ），and simplified coping style questionnaire (SCSQ)According to the test results，120 cadets were selected and categorized into 2 groups， high-trait anxiety group (n=51) and low-trait anxiety group (n=69). The differences of CERQ and SCSQ in these 2 groups were comparedResults     ①Compared with lowtrait anxiety group，hightrait anxiety group had higher state anxiety (P0.01) and more negative coping（P0.05)

and used more strategies of rumination

catastrophizing and otherblame (P0.01)Low-trait anxiety group had higher positive coping (P0.01) and used more strategies of refocus on planning and positive reappraisal (P0.01). ②The state-trait anxiety was positively correlated to rumination

catastrophizing and otherblame (P0.01)The state-trait anxiety was negatively related to positive refocusing，refocus on planning，positive reappraisal and positive coping(P0.05

P0.01)③Regression analysis showed that 4 cognitive emotion regulation strategies including rumination

positive refocusing，catastrophizing and otherblame

and 2 coping styles i.e. positive coping and negative coping

could significantly predict the state anxiety. Meanwhile

3 cognitive emotion regulation strategies including rumination

positive refocusing and catastrophizing

and both positive and negative coping styles could significantly predict the trait anxiety，which accounted for 276％ and 30.3％of the explanations

respectively.  Conclusion      The cognitive emotion regulation strategies and coping style are closely related to anxiety of military college students
