Abstract

The wetland ecological environment is in the interaction zone between fresh water and sea water, and has the function of purifying water bodies. As a large amount of sewage and waste are continuously discharged into the sea, the water purification function of the wetland is receiving increasing attention. Based on the relevant research results of domestic and foreign scholars, the research status of pollutant control methods and purification effects of wetland systems is reviewed. At present, the research on pollution ecosystem of wetland system mainly focuses on the impact of different pollutants on mangroves and ecological environment, including the growth and physiological ecology of mangrove plants, the accumulation and pollution of pollutants in mangrove plants. The effects on the sediments, algae, and benthic animals in the mangrove area. The research results shows that mangroves have strong tolerance to heavy metals, petroleum and sewage pollutants, and mangrove plants and soil under the forest have the ability to absorb a variety of pollutants, and have a strong purification effect on pollutants. The research on wetland systems needs to be further deepened. Wetland resources are in an endangered state, and management and protection need to be strengthened. All experimental projects should be carried out in non-protected areas.
