Progress of Researches on Wetland Ecosystems

Wetland ecosystems have gained more and more attention from ecologists for their important ecological functions and social-economic values in recent years.However,many wetland ecosystems all over the world have been lost or are facing a serious threat presently from natural and social factors.Wetland ecosystems are becoming a focus of ecology.In recent years,the studies on wetland ecosystems have concentrated on four main areas,i.e.,the investigations on basic information,dynamics, restoration and management of wetland ecosystems.Many new methods and techniques have been used widely in wetland ecosystem studies.The restoration and reconstructing methods of artificial wetlands,as well as their evaluation,have gotten more and more attention from scientists.Natural and social-economic factors may affect the function,structure,and dynamic of wetland ecosystems.Different types of wetland ecosystems have different characteristics.So it is necessary to conduct the study on structure,function and dynamics of wetland ecosystems in broader regions.Additionally,more attentions should be paid to the study of the key techniques(including selection of species) in restoration and rebuilding of wetlands.
