This invention provides a method for constructing an ecological lake wetland aquatic plant and animal community system. The method includes dividing the lake to be restored into two zones according to water flow direction and terrain. Then, bottom sediment improvement, planting of submerged plants, addition of amendments, and algae-controlling zooplankton are carried out in each zone. Ecological floating islands are constructed and emergent plants are planted. Aquatic animals are introduced, followed by routine management. Water purification devices containing EHBR membrane modules are installed near the lake inlet and in areas with higher terrain.
