GREENED WATER CHANNEL INCLUDING VEGETATION BASE
To provide a greened water channel including vegetation bases that can reduce a period until vegetation is formed after its construction as much as possible and allows native species to uniformly vegetate on the water channel wall face.SOLUTION: In a greened water channel 1 constituted by vegetation bases having a water retaining function, a seed sheet 4 in which seeds 12, 12... are disposed in a scattered manner between at least two laminated nonwoven fabrics 10, 11 is stretched along a wall face of the greened water channel 1, and a soil material 5 is charged into gaps between particles in the vegetation base 2 in at least the upper side area including a water channel side wall face of the vegetation bases 2, 2, to form a germination/growth promotion area 3. In the seed sheet 4, with the position of a water absorption height h1 in the vegetation base from an average water level of the water channel as a boundary line, by partitioning the lower side of the boundary line as an area A where water can be replenished from the water channel and the upper side of the boundary line as an area B where water cannot be replenished from the water channel, and seeds of native species plants with desiccation resistance are disposed in the area B where water cannot be replenished from the water channel.SELECTED DRAWING: Figure 2
【課題】植生基盤による緑化水路において、施工後に植生が形成されるまでの期間を極力短くすること、及び水路壁面に在来種が均一に植生されるようにする。【解決手段】保水機能を有する植生基盤により構成した緑化水路１において、少なくとも２枚の積層不織布１０、１１の間に散点状に種子１２、１２…を配置した種子シート４を前記緑化水路１の壁面に沿って張設するとともに、前記植生基盤２、２の水路側壁面を含む少なくとも上部側領域に、植生基盤２の粒子間空隙に用土系材料５を充填することによって発芽・生育促進帯域３を形成する。前記種子シート４において、水路の平均水位面からの植生基盤における吸水高さｈ１の位置を境界線として、その下側を水路から水分補給を受けられる領域Ａとするとともに、その上側を水路から水分補給を受けられない領域Ｂとして区画し、前記水路から水分補給を受けられない領域Ｂに在来種の乾燥耐性植物類の種子を配置する。【選択図】図２
