PROBLEM TO BE SOLVED: To provide a floating structure for biotope facilitating formation or maintenance of biotope via the combination of simple structures in a limited space or a place where a natural environment is hardly attained.SOLUTION: The floating structure for biotope includes: floating body units 20 each provided with a recessed part 21a to which a vegetation base 22 can be charged from above the top surface of a floating body, and a plurality of water flow holes 21b penetrating the bottom part of the recessed part 21a and the bottom surface of the floating body, and having a draft where the surface of water flooded in the recessed part 21a through the water flow holes 21b reaches the lower part of the vegetation base 22 while floating on the water surface and a water tank 10 having the depth deeper than that enough to secure the draft of the floating unit 20, and a planar area on which a plurality of the floating body units 20 can be disposed. The water tank 10 is charged with water to float the floating body units 20 and plants 40 are planted in the surface of the vegetation base 22 while the lower parts of the vegetation bases 22 soak in the water.COPYRIGHT: (C)2010,JPO&INPIT【課題】 限られたスペースや自然環境が実現しにくい場所において、簡易な構造体の組み合わせにより、ビオトープの形成・維持が容易に実現する。【解決手段】 植生基盤22を浮体上面から充填可能な凹部21aと、凹部21aの底部と浮体底面とを貫通する複数個の通水孔21bが形成され、水面に浮いた状態で通水孔21bを介して凹部21aに浸水した水の水面が植生基盤22の下部に達する喫水を有する浮体ユニット20と、浮体ユニット20の喫水が確保される以上の深さと、浮体ユニット20を複数個配列可能な平面積とを有する水槽10とを備える。水槽10内に給水し、浮体ユニット20を浮かせて植生基盤22の下部が浸漬した状態で、植生基盤22の表面に植物40を植栽する。【選択図】図2
