The invention relates to a construction method and a structural system of an inclined steel anchor beam on a cable-stayed bridge. The construction method comprises the following steps: processing to obtain a plurality of beam body sections forming the steel anchor beam; matching pieces are arranged on the beam body sections, and the beam body sections can be sequentially connected through the matching pieces to form the steel anchor beam; a mounting platform is built on the cable-stayed bridge main tower, and the top face of the mounting platform is perpendicular to the inclined direction of the cable-stayed bridge main tower; according to the mounting requirement of the steel anchor beam, the mounting position of the steel anchor beam on the building mounting platform is determined; according to the installation position of the steel anchor beam on the construction installation platform, the first beam body section of the steel anchor beam is vertically installed on the installation platform; and the remaini
