Description

Technical Field

[0001] The utility model belongs to the technical field of artificial wetlands, in particular to an artificial wetland secondary slope pond embankment. Background Art

[0002] Over the past 50 years, my country's wetland area has decreased and degraded significantly due to large-scale human exploitation of wetlands and climate change. Therefore, mitigating and preventing ecosystem degradation and shrinkage, and restoring and rebuilding damaged wetland ecosystems, have received significant attention. Supported by a series of national ecological and environmental strategic decisions, large-scale wetland restoration projects, such as the "Returning Farmland to Wetlands" initiative, have gradually been implemented.

[0003] Constructed wetlands promote biodiversity and provide a reservoir for growth, while also controlling the growth space for emergent plants and reducing operational and maintenance costs. The designed water depth for constructed wetlands is 0.4 to 2 meters. According to the "Wetland Park Design Standard" (CJJ / T308-2021), the normal water depth within 2.0 meters of the shore should not exceed 0.7 meters. However, existing constructed wetlands lack secondary slopes, resulting in water depths exceeding 0.7 meters within 2.0 meters of the shore, compromising safety for surrounding residents.

[0004] Therefore, this application proposes a secondary slope embankment of an artificial wetland. Utility Model Content

[0005] The purpose of the utility model is to propose an artificial wetland secondary slope pond embankment, so that the water level depth within 2.0m near the shore is not greater than 0.7m, thereby increasing the safety of nearby residents and ensuring the biodiversity of the wetland.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] An artificial wetland two-level slope pond embankment includes a first level slope, a first level platform, a second level slope and a pond bottom in sequence. The first level slope, the first level platform, the second level slope and the pond bottom constitute an artificial wetland structure. The first level platform is horizontally arranged at the bottom of the first level slope. The second level slope is the area connecting the first level platform and the pond bottom, where the shallow water area transitions to the deep water area. The main consideration is to limit the growth space of emergent plants and avoid excessive growth of emergent plants. The pond bottom is a deep water area.

[0008] Furthermore, the width of the first-level platform is ≥2m, and the water depth of the first-level platform is <0.7m.

[0009] Furthermore, the pond bottom is a concave structure.

[0010] Furthermore, the slope ratio of the primary slope to the secondary slope is ≥1:2.

[0011] Furthermore, grass seeds are spread above the water surface on the first slope.

[0012] Furthermore, native emergent plants or aquatic plants with economic value are planted on the first-level platform to improve the economic efficiency of the wetland.

[0013] Furthermore, submerged plants are planted at the bottom of the pond, mainly considering the natural recovery of submerged plants, improving wetland biodiversity, and building an underwater forest.

[0014] The utility model has at least one of the following beneficial effects:

[0015] The utility model is based on the safety, stability and biodiversity of the slope, combined with various aquatic plants that adapt to waters of different depths, and constructs multi-level platforms by cutting the slope. The shoreline line form and transition are more natural, gentle and ecological, and the aquatic plants form a certain distribution range in the water according to the different water depths.

[0016] The constructed wetland enhances biodiversity and serves as a reservoir, while also controlling the growth space for emergent plants and reducing subsequent operational and maintenance costs. According to the "Wetland Park Design Standard" (CJJ / T308-2021), the water depth within 2.0 meters of the shoreline should not exceed 0.7 meters. Considering the safety of surrounding residents and the wetland's biodiversity, the constructed wetland utilizes a secondary slope for its bank. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] An artificial wetland two-level slope pond embankment comprises a first-level slope 1, a first-level platform 2, a second-level slope 3 and a pond bottom 4 in sequence. The first-level slope 1, the first-level platform 2, the second-level slope 3 and the pond bottom 4 constitute an artificial wetland structure. The first-level platform 2 is horizontally arranged at the bottom of the first-level slope 1. The second-level slope 3 is the area connecting the first-level platform 2 and the pond bottom 4, where the shallow water area transitions to the deep water area. The main consideration is to limit the growth space of emergent plants and avoid excessive growth of emergent plants. The pond bottom 4 is a deep water area. The utility model is based on the safety, stability and biodiversity of the slope, combined with the adaptation of various aquatic plants to waters of different depths, and the slope is cut to build a multi-level platform. The shoreline line form and transition are more natural, gentle and ecological. Aquatic plants form a certain distribution range in the water according to the different water depths.
