The utility model relates to an ecological floating island device which can float on the liquid surface, and comprises a bearing unit and a plant cultivation unit.The bearing unit comprises a base and a ring seat extending upward from the periphery of the base.The base is matched with the ring seat to define a holding space, which has a bottom adjacent to the base and a top.The socket unit also comprises a partition at the bottom of the holding space and matched with at least one of the base and the ring seat to define a buoyancy chamber, and a plurality of main drain holes through the base and around the buoyancy chamber.The plant forming unit is contained at the top of the holding space of the bearing unit.The design of the holding space of the new model can provide for the growth of woody plants planted in the cultivation unit of the plant. In addition, the design of the buoyancy chamber can be used to reduce the demand of the cultivation unit of the plant for filling in the holding space, and further reduce the overall load to improve the overall buoyancy.一種生態浮島裝置能浮於液面，並包含一個承座單元，及一個植物養成單元。該承座單元包括一個底座，及一個自該底座周緣向上延伸的環座。該底座與該環座相配合界定一個容置空間，該容置空間具有一個鄰近於該底座的底部，及一個頂部。該承座單元還包括一個位於該容置空間的該底部且與該底座及該環座的至少其中一個相配合界定出一個浮力腔室的區隔件，及多個貫通該底座且位於該浮力腔室周圍的主排水孔。該植物養成單元容設於該承座單元的該容置空間的該頂部。本新型具有該容置空間的設計能供種植於該植物養成單元的木本植物生長，另外，具有該浮力腔室的設計能用來降低該植物養成單元填設於該容置空間的需求量，而進一步降低整體荷重以提升整體浮力。
