A reinforcing structure and a construction method for greening vegetation articles are provided. The reinforcing structure for greening vegetation articles comprises a vegetation article formed on a surface of an area to be greened, a locating cover (2), a locating component (3) and a rope (4). The locating component is pressed into the area to be greened. A rotating supporting pivot (31) is arranged on the locating component. One end of the rope is fixedly connected to the rotating supporting pivot, and the other end is exposed out of the area to be greened and passes through the vegetation article to reach the locating cover. The locating cover fixedly clamps the other end of the rope and presses the vegetation article. The rope can pull the locating component to rotate when the locating component is pressed into the area to be greened, which ensures that the locating component generates a large tension resistance in the area to be greened and can not be pulled out of the area to be greened easily. At the same time the locating cover is further pulled to tightly press on the vegetation article by the rope, so that the vegetation article can be firmly located on the surface of the area to be greened. The structure has good fixing effect and can effectively replace traditional anchoring rod.
