Embodiment 1
[0042] The construction method of the near-natural reverse osmosis biological wall in the lake water-fluctuation zone of the present embodiment is based on the distribution state of the plant community, and includes the following four parts according to the length of the flooding time:
[0043] Area A: arbor, shrub and grass belt (very little flooded area), that is, arbor layer + shrub layer + herbaceous plants;
[0044] Zone B: Shrub and grass zone (short flooding time, moist land), that is, shrub layer + herbaceous plants;
[0045] Area C: emergent plants + floating plants area;
[0046] Zone D: submerged plants + biological wall zone (water level fluctuation zone).
[0047] Among them, the flooding time of area A is the shortest, and the flooding time of area D is the longest.
[0048] Aquatic plant community construction in degraded wetlands:
[0049] The submerged plants selected in this embodiment and their planting densities are respectively hornwort ( Ceratophyllum ...
