The invention provides a light-cured surface functional gradient coating and a construction method thereof, and the construction method comprises the following steps: coating an area to be coated with a layer of paint with the thickness not greater than H0 in a formula 4, carrying out light curing by adopting a light source, repeating the coating and the light curing for N-1 times, and carrying out heat treatment to obtain the light-cured surface functional gradient coating. A coating with the total thickness being H is obtained in the to-be-coated area; in formula 4, X is determined by formula 3. Wherein the coating curing parameter transmission depth coefficient Dp and the critical exposure rate Ec in the formula 3 are calculated through the formula 2. The technical problems that in an existing photocuring SFGM technology, the preparation time of a surface layer is too long, and a thick coating is difficult to obtain at a time are solved. 本发明提供了一种光固化表层功能梯度涂层及其构建方法，所述构建方法包括以下步骤：于待涂覆的区域，涂覆一层厚度不大于式4中的H0的涂料，采用光
