1. An atomization assembly, comprising:
a substrate comprising an atomizing surface on which an aerosol-forming matrix is atomized to form aerosol; and
a heating element configured to be connected to a power source to heat and atomize the aerosol-forming matrix at the atomizing surface, the heating element being directly or indirectly arranged on the atomizing surface;
wherein the heating element is divided into a plurality of first heating sections and a plurality of second heating sections, the plurality of first heating sections all extending along a first direction and being spaced in a second directions perpendicular to the first direction;
