The invention relates to the technical field of instrument fault diagnosis, in particular to a method for testing failure misalignment of a wind meter in a wind-blown sand environment, which comprises the following steps of: firstly, acquiring a wind condition and a sand-dust curve of an operation position of the wind meter, and acquiring sand-dust data and wind condition data of the operation position of the wind meter through the wind condition and the sand-dust curve; according to the method, a wind tunnel experiment is deployed through the sand and dust data and the wind condition data of the operation position of the wind meter, then the standard wind meter is used for testing, the deviation between the tested data and the collected data is compared, and the problem of the wind meter is found out. The wind condition and sand and dust data of the wind meter only need to be collected in the corresponding environment, and the subsequent testing work is carried out in the wind tunnel experiment; according to
