9. The coastal ecological landscape structure according to claim 1, characterized in that branches adopted by the latticed branch structure are waste branches trimmed off by garden nursery stocks.
10. A construction method of the coastal ecological landscape structure according to any one of claims 1 to 9, characterized by comprising the following steps:
s1, building a stone layer at the downstream position of the embankment to enable the stone layer to have a preset gradient;
s2, adopting caulking, compacting and leveling of sludge on the basis of the stone building layer to form a sludge layer with the thickness of 50-100 mm;
s3, paving a geotextile layer on the basis of the sludge layer to prevent the soil loss caused by scouring of the planting soil along with tides and waves;
s4, laying a planting soil layer with the thickness of 400-500mm on the geotechnical cloth layer as a space for plant growth and implantation, laying a plurality of grid-shaped branch structures formed by bundling branches with the diameter of 150mm above the planting soil layer, and filling planting soil in the grids of the branch structures;
s5, cultivating plants in planting soil, and binding the plants on branch bundles at intervals of 1000mm by using geotechnical ropes;
s6, integrally covering the latticed branch structures and the upper parts of the planting soil with gravels with the particle size of 10-20mm to form a gravel layer, and preventing the planting soil on the surface layer from being washed by water flow;
s7, after compacting and leveling the downstream foundation of the stone building layer, stacking a plurality of ecological bags to form a first stable foundation layer;
s8, planting hygrophyte or lianas, mangrove plants and semi-mangrove plants on the compacted and leveled sludge beach to form a first plant zone, and stacking a plurality of ecological bags at the downstream of the first plant zone to form a second stable base layer;
and S9, stacking stone blocks with preset gradients at the downstream of the second stable foundation layer.
