The invention relates to a forming and shape-preserving thermal treatment method for an aluminum-based alloy thin-wall component with a complex structure. The method comprises the following steps: separately uniformly coating a solder resist on the two end surfaces of each of a first tool, a second tool and a third tool, and sequentially stacking the first tool, the second tool and the third toolin a mold to subject to first-time heating and pressurizing treatment, thereby obtaining a thermal treatment tool of the first tool and a thermal treatment tool of the third tool; putting an aluminum-based composite material superplastic board and the punched third tool into the mold for second-time heating and pressurizing treatment, thereby obtaining the aluminum-based alloy thin-wall componentwith the complex structure; stacking the first tool, the third tool and the aluminum-based alloy thin-wall component with the complex structure in a set order to form a three-layer structure; and cooling the thermally-treated
