Wetland consists of natural wetland system and man-made wetland system. According to hydrology, landform, soil and vegetation
etc., natural wetland can be divided into the following types: marine, esturine, riverine, lacustrine, palustrine subsystems.
On the basis of the wetland bottom compound, waterlogged state and vegetation forms, it can be subdivided into 26 wetland
classes. Man-made wetland can be subdivided into 4 wetland classes. Wetland is a unique landscape in the earth and one of
the most important living environment with rich resources and many functions. At present, 262 different types of Wetland Natural
Reserves have been established in China, in which 7 Wetland Nature Reserves have been listed in international important wetlands
of “The Wetland Convention”.
