[0021] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described clearly and completely below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments derived by persons of ordinary skill in the art without inventive effort are also within the scope of protection of the present invention.

[0022] The specific implementation of the present invention will be described below with reference to the accompanying drawings:

[0023] like Figures 1 to 4 As shown, a landscape structure for improving a water body includes a revetment 1 and a stormwater filter strip 2. Revetment 1 includes a downslope 11, a wetland 12, and an upslope 13. Downslope 11 extends into the water body, with wetland 12 located between them. A stormwater filter strip 2 is located on top of upslope 13. From the bottom of the water body to the stormwater filter strip 2, a submerged plant belt 7, a floating plant belt 6, an emergent plant belt 5, a shoreline wetland zone 4, and a turf belt 3 are arranged in sequence. The stormwater filter strip 2 mitigates the impact of rainwater erosion on revetment 1, preventing soil erosion and water quality. The various plants solidify the topsoil layer of revetment 1, maintaining its stability. They also absorb nitrogen, phosphorus, and other elements from the water, preventing eutrophication. They provide habitats for insects, aquatic animals, amphibians, and other species, enhancing the overall ecological diversity of the landscape structure. Furthermore, the plants beautify the waterscape and increase its appeal.

[0024] The stormwater filter belt 2 comprises a first gabion 21 and a gravel layer 24. The gravel layer 24 is located at the top of the upslope 13, with the first gabion 21 positioned above the gravel layer 24. The first gabion 21 resists the initial, significant kinetic energy of rainwater, while the gravel layer 24 further buffers and absorbs the rainwater, ensuring the overall integrity and scour resistance of the stormwater filter belt 2. The slope of the first gabion 21 is less than that of the upslope 13, increasing the time that falling rainwater remains in the stormwater filter belt 2. Excessive rainwater can damage the revetment 1 structure. A second gabion 22 is positioned on one side of the gravel layer 24. Geotextiles 241 are placed on the bottom surface of the gravel layer 24 near the upslope 13 and on the top surface of the first gabion 21. The geotextiles 241 maintain the stability of the gravel layer 24, while the second gabion 22 prevents the loss of the gravel layer 24 from the sides. The bottom of the first gabion 21 is equipped with multiple evenly distributed fixing piles 23. The tops of the fixing piles 23 are fixedly connected to the first gabion 21, and the bottoms of the fixing piles 23 pass through the gravel layer 24 and extend into the uphill slope 13. The multiple fixing piles 23 maintain a stable position between the rainwater filter belt 2 and the revetment 1.

[0025] The surface of the upslope 13 is provided with a turf belt 3, which covers the surface of the upslope 13. The types of turf belt 3 include bluegrass, pennisetum, and communis. The rooting ability of the turf belt 3 is used to solidify the topsoil layer of the upslope 13 and buffer the kinetic energy of rainwater erosion, thereby protecting the integrity of the shape of the upslope 13. There are various marsh-type plants in the 4 shore wetlands, including taro, reed, and buttercup. The wetland 12 has the function of storing flood water, and at the same time provides a good habitat for insects, birds and other animals, thereby enhancing the ecological diversity of the landscape structure.

[0026] The downhill slope 11 is provided with multiple evenly spaced grooves 111, within which multiple binding strips 112 are provided, and along the length of the binding strips 112, multiple straps 114 are provided. Multiple evenly spaced fixing blocks 113 are provided along the length of the grooves 111, each with spikes at both ends. The fixing blocks 113 are inserted into the downhill slope 11 via the spikes and press the binding strips 112 into the grooves 111. The downhill slope 11 is located in a body of water. By providing multiple binding strips 112 and grooves 111, the basic shape of the downhill slope 11 is solidified, preventing soil erosion on the downhill slope 11. The downhill slope 11 is provided with an emergent plant belt 5, which includes calamus, reed, and water plantain. The rooting ability of the emergent plants can enhance the stability of the downhill slope 11.

[0027] A floating plant belt 6, consisting of water hyacinth, duckweed, and water fern, is installed 10.5 meters above the revetment. A submerged plant belt 7, consisting of hornwort, foxtail algae, and water sieves, is located at the bottom of the water. These two belts prevent eutrophication, optimize the habitat for aquatic life, and effectively purify the water.

[0028] The working principle of the specific embodiment of the present invention is: by arranging a rainstorm filter belt 2 on the top of the revetment 1 to prevent the erosion of the revetment 1 by rainstorm, solidifying the shape of the revetment 1 through plant belts at various levels, purifying the water quality, beautifying the landscape structure and improving ecological diversity.
