Wetland,with important ecological functions and values,is an ecological landscape rich in biodiversities and one of the most important habitats for man.Wetlands serve as source,sink or transfer of nitrogen,and concentrations,movement and transformation of nitrogen in wetland soils will significantly influence the structures and functions of wetland ecosystems.Hence study on nitrogen in wetland soils has become one of the hot spots at present.Nitrogen is one of the indictors of nutrient level in wetlands.Studies on nitrogen contents in wetland soils,nitrogen retention in wetlands and processes of nitrogen movement and transformation were reviewed in this paper.
