There is plenty of nitrogen, phosphorus and heavy metal pollutants in artificial wetland in the subsided coal-mining areas, aquatic plants are the best choice to restore the site. Through investigation and analysis, it was found that emergent plants of Phragmites australis and Acorus calamus, floating-leaved plants of Hydrocharis dubia, and submerged plants of Ceratophyllum demersum, Potamogeton malaianus, Potamogeton crispus growing in Jiuli artificial wetland. The aquatic plants in Jiuli lake purified the water through adsorption and absorption, effectively reducing the concentration of suspended matters and the turbidity of water, increasing the transparency and dissolved oxygen of water, and therefore effectively inhabiting the growth of algae
