Layout method for coastal vegetation patches

Abstract

The invention discloses a coastal side vegetation patch layout method, and belongs to the technical field of coastal engineering. Comprising the following steps: S1, collecting statistical data of wave conditions of a salt marsh vegetation sea area under extreme weather; s2, determining planned planting axis positions of coastal side salt marsh vegetation patches; s3, determining the size and the arrangement form of the coastal side salt marsh vegetation plaque according to the wave wavelength and the incident angle collected in S1; s4, ecological reefs are filled between the interiors of the plaques to be planted on the coastal side salt marsh vegetation and the plaques. According to the method, wave energy is averaged through nonlinear periodic vegetation plaque arrangement, wave field distribution is reduced, the wave height is reduced, erosion of waves to the coast is reduced, and the effect of coast soft protection is achieved. Meanwhile, impact and damage of long waves to salt marsh vegetation of coastal vegetation patches under extreme disasters are weakened, and the self-repairing capacity of the salt marsh vegetation is improved compared with that of traditional arrangement.

Description

technical field [0001] The invention relates to the technical field of coastal engineering, in particular to a method for arranging vegetation patches on the seaside. Background technique [0002] Salt marsh vegetation has important theoretical significance and practical economic significance for the research and application of coastal soft protection: 1. Promote soil formation by trapping debris, resist the impact of tides and floods, and protect embankments; 2. Filter land runoff 3. Provide ideal habitats for habitat and foraging for many marine animals (including fisheries, aquatic organisms); 4. Be the main producer of organic debris for offshore productivity; 5. , The products of plants themselves, including wood, fuel charcoal, food, medicinal materials and other chemical raw materials; [0003] The main feature of the flexible revetment method for salt marsh vegetation is that it conforms to the changing trend of nature to prevent the loss of coastal sand and soil, a...

Problems solved by technology

The function of bioengineering revetment is mainly reflected in the ability to eliminate wave energy, slow flow to promote silt and foundation consolidation. Ecological revetment has little impact on the ecological environment of the coast. Even if the project is implemented, there is still room for change, and the cost is relatively low. In the attack of strong wind and waves, there is not much protective effect

When extreme disasters such as storm surges occur, the wavelength of the wave becomes larger and the wave energy increases sharply, which will quickly lead to the destruction of vegetation and cannot repair itself
