The invention discloses an assembly-type vertical greening wall body. The assembly-type vertical greening wall body comprises a wall body; a plant planting groove is formed in the wall body; a waterproof layer is arranged on the inner wall of the plant planting groove; and the outer side of the wall body is provided with a growth window communicating with the plant planting groove. According to the greening wall body disclosed by the invention, the problem that a conventional concrete wall cannot meet the concept of three-dimensional greening is solved. Buildings are fully integrated into natural environments, and the assembly-type vertical greening wall body accords with the design concepts of energy-saving buildings and green buildings in China. Building energy consumption is reduced, the urban greening area is increased, buildings are beautified, wind and dust can be prevented, air can be purified, noise can be reduced, and the urban heat island effect can be relieved.
