摘要
Wetlands are special ecosystems with distinctive biogeochemical circulation.Wetland soil locates where biogeochemical conversions take place,and its Eh value strongly influences the biogeochemical conversion procedure of elements. This paper analyzed the biogeochemical conversion procedure of essential elements such as C,N,P and S,the main environmental factors influencing the biogeochemical circulation in wetlands,and summarized important characters of the biogeochemical circulation in wetlands.It is concluded that controlling pollution and reinforcing conservation and management of wetlands will keep positive biogeochemical circulation in wetlands.
