The present invention relates to a vegetation block and, more specifically, to a vertical construction-type vegetation block and a vegetation block construction method. When vegetation blocks are constructed, a vegetation space is secured when vegetation blocks are naturally piled up regardless of upper and lower vertical line construction or crossing construction. Therefore, the construction thereof is very convenient, and in particular, the binding force of soil charged in the vegetation blocks, which are adjacent to each other, is increased through the vegetation space extended through the upper and lower parts and the extension grooves of the vegetation space formed on both sides, thereby enabling firm construction. The binding force between soil filled in each vegetation block is increased, thereby securing stability. In addition, the vegetation space is opened through a vegetation inducing groove recessed inwardly in the front surfaces of the vegetation blocks, and thus plant planting is very convenient. In particular, in the case of vertical construction, a planting hole is formed, and thus a variety of large and small plants can be vegetated. Also, the vegetation space of the vegetation block is connected to the raw ground through the watering pipe even when a crushed stone is used during rear filling of the vegetation block in the construction process, thereby preventing the plants from being damaged due to the lack of moisture by inducing the moisture of the raw ground to the vegetation space. In addition, the upper part of the vegetation space forms a roof shape through the vegetation block, and a loss prevention projection is formed on the front surface of the exposed vegetation space. The soil is prevented from being lost due to rainwater or the like.발명은 식생블록에 관한 것으로, 더욱 상세하게는 식생블록을 시공함에 있어, 식생블록을 상,하의 수직선상 축조나 교차 축조에 상관없이 자연스럽게 쌓기만 하면 식생공간이 확보되는 것인바, 그 시공이 매우 편리하며, 특히 상,하 관통된 식생공간 및 양측에 형성되는 식생공간 확장홈을 통해 상,하,좌,우 이웃하는 식생블록에 충전되는 토양의 결속력을 증대시켜 견고한 시공 및 각
