The mud of the bottom of a lake of a reproduced place, containing nutrient 20 of submerged plants 200a is painted and put in the front side of the three-dimensional void structure of the planting base 100 and is dried so as to prevent as much as possible flaking of the nutrient 20.例文帳に追加

植栽基盤１００の３次元の空隙構造の表面側に、沈水植物２００ａの栄養物２０を含んだ再生箇所等の湖底の泥を塗り込み、その後乾燥させて、栄養物２０の剥落を極力防止する。 - 特許庁

To provide a structure of an environment conservation block for rivers and channels which can create a space (a biotope) extremely suitable for growing of not only aquatic animals such as fish but also plants such as submerged plants and emergent plants in natural rivers and artificial channels and has an extremely high degree of contribution to natural environment conservation.例文帳に追加

自然の河川や人工の水路において、魚等の水生動物のみならず沈水植物や抽水植物等の植物の生育にとっても適した空間（ビオトープ）を創り出すことを可能とする、自然環境保全に対する貢献度が極めて高い河川水路用環境保全ブロック構造を提供すること。 - 特許庁

To reduce decrease in raising function of a vegetation mat or water pollution which is caused by outflow of soil in a vegetation base into water, and reduce cost for regenerating the community of the submerged plants on the water bottom in a closed water area.例文帳に追加

The artificial fish bank has a shell wall having a projecting curved outer face, an inner space formed in the shell wall and growing and proliferating marine plants in a state submerged to a sea bottom, an opening formed on a ceiling of the shell wall to open the inner space, and a plurality of holes formed on a peripheral part of the shell wall and penetrated to the inner space.例文帳に追加

この人工魚礁は、外面が凸状の曲面形状を呈する殻壁と、殻壁の内部に形成され、海底への沈設時に海中植物を育成し繁殖するための内部空間と、殻壁の天井部に形成され内部空間を開放するための開口と、殻壁の周縁部に形成され内部空間に貫通する複数の孔とを有する。 - 特許庁

The fence 1 can prevent inflow of contaminated water around a place where phytoplankton such as water-bloom appear or contaminated water to easily generate phytoplankton such as water-bloom, and block waves, so it is possible to surely grow the submerged plants 2 in the fence 1 to form clusters, and gradually expand the flourishing area by expanding the fence 1.例文帳に追加

囲い１によって、アオコなどの植物プランクトンの発生した周りの汚濁水またはアオコなどの植物プランクトンが発生しやすい汚濁水の流入を防ぎ、波浪を遮ることができるため、囲い１内で確実に沈水植物２を成長させて群落を形成し、その繁茂領域を囲い１の拡張によって漸次拡大させていくことができる。 - 特許庁
