According to the floating wetland bed provided by the embodiment of the application, the fiber carrier 100 floats on the water surface, the anchoring assembly positions the position of the fiber carrier 100, and aquatic plants planted in the aquatic plant growing area can purify the surrounding water body.

It can be understood that, the water body purification by the aquatic plant belongs to the prior art in the field, on one hand, the root system of the plant extends into the water body, and the root system and the microorganism attached on the root system act together, so that the inorganic pollutant in the water body can be adsorbed, the heavy metal content of the water body can be reduced, the organic pollutant in the water body can also be absorbed and decomposed, and the eutrophication phenomenon of the water body can be reduced; on the other hand, the root system can be used as a habitat of animals such as fish, shrimps and the like, and the fiber carrier can be used as a habitat of animals such as insects, frogs and the like, so that the stability of the ecological system of the water body is improved; moreover, the aquatic plants can also play a role in landscape.

The slope protection plant planting area 110 with the slope 111 has the following beneficial effects: firstly, the water waves which impact the fiber carrier 100 are attenuated continuously along with the increase of the moving distance, so that the planting position of the aquatic plants is far away from the edge of the fiber carrier 100, and the possibility that the water waves impact the aquatic plants can be reduced; secondly, plant the grass 310 of bank protection in bank protection plant species district 110, the blade of the grass 310 of bank protection overlaps each other, form the three-dimensional spatial structure who has the hole of a take the altitude, can play certain unrestrained effect that disappears, the wave can be the decay with higher speed when the grass 310 of bank protection, further reduce the possibility that the wave impacted aquatic plant, slope 111 of slope can increase the planting area of the grass 310 of bank protection, strengthen the barrier effect of the grass 310 of bank protection, the wave also has the decay of certain degree when climbing high on slope 111.

Fig. 2 is an example of one shape of the fiber carrier 100, and the fiber carrier 100 may be designed in other various shapes as required.

Referring specifically to fig. 3, in some embodiments, the angle of the ramp 111 may specifically be 45 °. In some embodiments, to ensure the wave-breaking effect of the revetment plant growing area 110, the width of the revetment plant growing area is not less than 0.45m.

It is understood that, here, only the minimum value of the width is limited, and the widths of the slope-protected plant growing region 110 and the slope 111 at different positions can be adjusted adaptively according to the shape of the fiber carrier 100 and the position of the fiber carrier 100 in the water body. The width of the revetment plant growing section 110 and the slope 111 may be increased appropriately at a portion which is easily impacted by water waves or where water waves are strong.

For example, taking the fiber carrier 100 of fig. 2 as an example, in some embodiments, the fiber carrier 100 has a strip shape, and when placed in a water body, the length direction of the fiber carrier 100 is arranged in the same direction as the water flow. This makes the area of the surface of the fiber carrier 100 facing the water flow smaller, which can reduce the impact of the water waves on the fiber carrier 100 and improve the stability of the floating wetland bed.

In such a scenario, the position greatly impacted by the water wave is the side facing the water flow direction in the length direction of the fiber carrier 100, so the width of the slope protection plant growing area 110 and the slope 111 on the side can be properly increased; the positions with less water wave impact are two sides of the fiber carrier 100 in the width direction, the positions with less water wave impact are the sides of the fiber carrier 100 in the length direction, which are back to the water flow direction, and the widths of the slope protection plant growing area 110 and the slope 111 at the positions can be properly reduced compared with the side facing the water flow direction on the premise that the widths are not less than the minimum value.

To enhance the slope protection effect, in some embodiments, the grass 310 is manila. Zoysia japonica is named as zoysia matrella, is suitable for growing in a humid environment, has the characteristics of developed root system, high weather resistance and high salt resistance, can well grow in a polluted water body and resist the impact of water waves, and plays a role as the slope protection grass 310.
