The invention discloses a method for quantitatively evaluating the form of a cigarette combustion cone. The method comprises the following steps: preparing a cigarette sample; making a combustion conefor the cigarette sample; obtaining an image of the combustion cone; and acquiring the cone height, the cone top angle, the left corner value, the right corner value and the cone area value of the combustion cone through the image. The method is simple and quick, and provides method support for regulating and controlling the shape of the cigarette combustion cone, improving the cigarette combustion state and improving the comprehensive quality of cigarettes.
