Wetland protection and research is becoming a hot spot. The concept of generalized wetland, which is gradually accepted by people, has innovated the traditional classification system of earth environment. The primary classification of ecosystems in the earth's biosphere has changed from ocean and land to ocean, wetland and land. Wetland is the only ecosystem with the confluence of four circles (atmosphere, hydrosphere, geosphere and lithosphere) among the three ecosystems. The close relationship between it and human survival is surprising.
the reason why wetland conservation and research has become a hot spot?
