| Abstract: | Wetland is the very important natural resource and it is one of the important living environments for humans and wild propagations.The biodiversity is very rich in wetlands.There were thousands of histories for wetland researches.There were several processes of wetland researches which include from observation to long-term location experiments,from investigation to structure,function and process,and from research on marsh to research on all kinds of wetlands.Wetland researches have their own characteristics in China and have gained great advancements in recent years.It reviewed our own research results in China in nearly thirty years.It mainly included seven aspects,such as concepts and classifications of wetland,formations and development rules,the hydrological processes and function which represented providing space for water storage,pollution reduction and water purification,biogeochemical cycles which represented greenhouse gases emissions,metal elements migration and nutrients withholding,succession of vegetation communities in which the species diversity always changed and it declined when up to climax communities,services value estimation,and finally research on soil carbon fraction in wetland cultivation and reverting farmland to wetland.It puts forward the main problems in wetland research which include the weakness of wetland basic theories,the lack of wetland classification systems suitable for Chinese wetland types and the shortage of long-term orientation observations of wetland ecosystem.So suggestions about wetland researches in the future are proposed from two aspects which were the construction of wetland science system info should be strengthened and the directions of wetland research. |
