Wetland is a transitional zone between terrestrial ecosystem and aquatic ecosystem. In the specific environment where the soil is immersed in water, many wetland characteristic plants grow. Wetlands are widely distributed around the world, with many wild animal and plant resources. They are important ecosystems. Many rare waterfowl cannot breed and migrate without wetlands, so wetlands are called "paradise of birds". Wetland has a strong ecological purification function, so it is also known as the "kidney of the earth". Under the dual pressure of population explosion and economic development, a large number of wetlands were transformed into farmland in the middle and late 20th century. With excessive resource development and pollution, the wetland area was significantly reduced, and wetland species were severely damaged.
Wetland is a multifunctional and biodiversity rich ecosystem on the earth, and is one of the most important living environments for human beings.
Wetlands are of various types, usually divided into natural and artificial. Natural wetlands include marshes, peatlands, lakes, rivers, beaches and salt marshes, while artificial wetlands mainly include paddy fields, reservoirs, ponds, etc. According to statistics, there are 8.558 million square kilometers of natural wetlands in the world, accounting for 6.4% of the land area.
