Research for wetland network used to improve river water quality

摘要

Pollutants discharged as a result of urbanization have created a series of environmental problems, especially deterioration of water quality, which influence human health. Water quality improvement has become an urgent priority in water resource management. As "the kidneys of earth," wetlands have been widely used in pollution control. To make the wetland play a better role in reducing pollution, various methods have been developed in recent years, especially wetland networks. Major factors influencing the functions of wetland are wetland categories, wetland area, wetland site and wetland hydrology, which are sometimes related to flood and dry seasons. Using wetland networks to improve water quality is an important and urgent work for environment protection, and also provides a useful method for water managers.
