1. An ecological restoration method for wading bird habitat in coastal mudflat wetland, characterized in that, comprising the following steps:
S1. performing micro terrain renovation on a candidate area of coastal mudflat wetland, to make ground slope from land to sea in the candidate area ≤5°, and restoring matrix in the candidate area;
S2. controlling water level of water of regions except for wading bird habitats in the candidate area at 5-15 cm, with the water surface area of the regions except for wading bird habitats accounting for 40-60% of the candidate area;
S3. controlling vegetation coverage of the candidate area to be ≤30% and ≥10%, with vegetation height of ≤50 cm, planting or restoring salt tolerant vegetation areas;
S4. selecting or restoring ecological pinch points or ecological barrier points in the candidate area to construct ecological corridors;
S5. constructing wading bird habitats in the candidate area; the wading bird habitat includes 2-3 bare flats with an area of ≥0.2 km2, ecological ditches with a width of 1.5-2.5 m and a depth of 0.5-1.2 m, 3-4 deep water areas with an area of ≥0.5 km2 and a depth of 1.8-3.5 m, and 5-6 shallow water areas with an area of ≥0.5 km2 and a depth of 8-15 cm; connecting deep water areas and shallow water areas through ecological ditches.
