A river, lake or beach habitat protection system according to claim 1, wherein: The bottom of the submerged maze is filled with a gravel protection layer (1034), the frame of the aquatic plant unit (2) is filled with a surface cultivated soil (203), and the surface cultivated soil (203) is planted with aquatic plants (204).

6. A method for constructing a river-lake beach habitat protection system according to any one of claims 1-5, characterized in that The method comprises the following steps: S1, installing the habitat protection plastic steel sheet pile (3) in the river or lake beach first, and then installing the separation plastic steel sheet pile (4), wherein the habitat protection plastic steel sheet pile (3) is spliced with the separation plastic steel sheet pile (4) at the corresponding position, and forms the frames of the habitat units (1) and the aquatic plant units (2), wherein the habitat units (1) and the aquatic plant units (2) are distributed alternately; S2, forming a submerged maze in the frame of the habitat unit (1), connecting the submerged mazes of adjacent habitat units (1), putting aquatic animals (1035) and microorganisms in the submerged maze, and planting aquatic plants (204) in the frame of the aquatic plant unit (2).

7. The construction method of the river or lake beach habitat protection system according to claim 6, wherein: between steps S1 and S2, the following steps are further included: excavating the area surrounded by the frame of the habitat unit (1), installing the porous plastic steel sheet pile (1051) in the excavated area, forming the frames of the adsorption and precipitation areas (105), backfilling the gravel filler (1052) in the frame of the adsorption and precipitation area (105), and forming the adsorption and precipitation areas (105). The step S2 specifically comprises: backfilling a gravel protection layer (1034) in the excavation area of the submerged tunnel, filling a surface cultivated soil (203) at the bottom of the frame of the aquatic plant unit (2), fixing a plurality of steel pipes (1041) on the habitat protection plastic steel sheet pile (3) in the middle of the habitat unit (1), the steel pipes (1041) being perpendicular to the extension direction of the normal projection of the habitat protection plastic steel sheet pile (3), hanging a plurality of fishbone-shaped fiber strips (1046) at the lower end of the steel pipes (1041) to form a breeding habitat for microorganisms, planting aquatic plants (204) on the surface cultivated soil (203), and releasing aquatic animals (1035) and microorganisms above the gravel protection layer (1034) of the submerged tunnel.
