Advances in Researches on Biogeochemical Circulation of C,N and P in Wetlands

It is the core content to study the biogeochemical circulat io n in wetland in the researches on the wetland ecosystem function.The critical pr ocesses research was developed to investigate the interactions between physical, chemical and biological processes and the relationships between these processes and wetland functions.This paper analyzed the biogeochemical procedures of essen tial elements such as N,P,C,the biogeochemical circulation in wetland.The paper also briefly analyzed the prospects in researches on biogeochemical circulation in wetlands.
