The green energy plant and plant composite structure system (2) in this creation at least includes: roof system, roof slab,It is arranged above the support system；One side of the groove part of the roof board is provided with a first sealing sheet and a second sealing sheet.A planting space is formed on one side of the first sealing piece to store water and plant.And a water guide is arranged between the first sealing sheet and the second sealing sheet.To connect with the water conduit,Let the water in the adjacent groove be S-shaped.And a water outlet is arranged outside the second sealing sheet.To connect with the drainage pipe,The excess water shall be led into the drain pipe for discharge；Plant elements,In the groove of the said roof slab,To plant all kinds of plants；Support system,Set up steel beams.Set in a vertical direction to the roof slab.A vertical supporting steel frame is arranged above the steel beam.To support under the peak part of the roof slab,Then the structure of supporting steel frame is lifted by reinforcing steel frame.So,The green energy planting system can be formed on the roof of the building.Increase the green planting area.Conform to the innovative structure of environmental protection building.本創作之綠能植栽複合結構系統(二)，至少包含：屋頂系統，設屋頂板，被設置於支撐系統上方；前述屋頂板之槽部一側設第一封閉片與第二封閉片，位於前述第一封閉片之一側形成植栽空間以儲存水分與植栽，且於前述第一封閉片與第二封閉片之間設導水口，以與導水管銜接，讓相鄰之槽部的水以類S形導流，再於前述第二封閉片外側設排水口，以與排水管銜接，得將多餘的水導入排水管排出；植栽元件，設於前述屋頂板之槽部，得為各類植物栽種其中；支撐系統，設鋼樑，以與前述屋頂板呈現垂直方向設置，前述鋼樑上方設垂直向之支承鋼架，以支撐於屋頂板之峰部部分下方，再藉由補強鋼架提升支承鋼架之結構；如此，得於建築物屋頂之形成綠能植栽系統，增加綠色植栽面積，符合環保建築之創新結構。
