A vertically-greening vegetation structure comprises a modeling frame vertically disposed outside a building, at least one cultivation box, and an irrigation unit. The modeling frame comprises a plurality of modeling channels that are communicated with inner and outer sides of the building and a rail that is disposed on a bottom thereof for lateral movement. The cultivation box, which is slidably disposed on any of the modeling channels of the modeling frame for cultivating a plant, comprises a water drainage hole disposed on a bottom thereof. The irrigation unit comprises a water collection tank that is disposed on a top end of the modeling frame for collecting rainwater, a water storage tank that is disposed under the modeling frame, at least one water drainage plate that is disposed under the cultivation box, and a water diversion duct that is utilized for guiding water of the water collection tank to the cultivation box and for guiding the water of the water drainage plate to the water storage tank. Accordingly, with the configuration of the vertically-greening vegetation structure, a convenient maintenance and management and a self-irrigation function can be obtained.一種垂直綠化的植生構造,包括:一造型框架,直立設置於建築物的外側,造型框架具有多個連通建築物內外側的造型通道,造型框架的底部設有軌道以便橫向移動;至少一栽培盒,栽培盒以可滑動的關係設於框架的任一造型通道用於種植植物,栽培盒的底部具有排水孔;一澆灌單元,包含設於框架頂端的一集水槽用於收集雨水,設於框架下方位置的一儲水槽,至少一位於栽培盒下方的排水盤,和一導水管用以將集水槽的水引導至栽培盒以及將排水盤中的水引導至儲水槽;透過上述的構造提供一種方便維護管理並且具有自我灌溉功能的垂直綠化的植生構造。10‧‧‧造型框架11‧‧‧造型通道111‧‧‧第三排水孔14‧‧‧軌道座20‧‧‧栽培盒21‧‧‧外盒22‧‧‧內盒31‧‧‧集水槽32‧‧‧儲水槽321‧‧‧排水閥322‧‧‧排水管33‧‧‧排水盤34‧‧‧導水管40‧‧‧承載平台41‧‧‧承載面411‧‧‧洩放孔42‧‧‧軌道42a‧‧‧軌道P1‧‧‧卡榫P2‧‧‧卡榫槽
