The utility model provides a data analytical method and a system of pollen images, comprising image data processing of pollen grains (drawing of straight or curve line in the image data of pollen grains), drawing of various figures, character deepening and/or filling, pseudocolor processing, revolving and duplicating of the image data of pollen grains, moving of whole or part of the image data ofpollen grains, amplifying and reducing with interpolation of the image data of pollen grains. Then the amount data of the pollen grains is obtained through the identification measurement, breaking through and classification of the image data of pollen grains after image processing. The obtained amount data of the pollen grains is processed with data statistics. At last, the amount data of the pollen grains after data statistics is processed with data analysis and the result after data analysis processing can be gained. The utility model can solve the problem of low efficiency of artificial pollen monitoring analysis and inaccuracy of the pollen monitoring result.
