The invention provides a method for identifying different pollution sources by using thermogravimetric analysis, which comprises the following steps: establishing a thermogravimetric database of a macular tobacco standard sample, and identifying, the establishing of the thermogravimetric database of the macular tobacco standard sample comprises the following steps: (1) preparing the macular tobacco standard sample, (2) establishing a thermogravimetric database, and (3) establishing the thermogravimetric database of the macular tobacco standard sample. (3) replacing the potential pollution sources, and repeating the steps until a thermal weight loss database of a plurality of potential pollution sources of the cigarette cut tobacco production line is established; the identification process comprises the following steps: (4) obtaining the thermal weight loss and characteristic parameters of the cigarette paper of the yellow-spot cigarettes occurring in actual cigarette production; and (5) judging the source of
