Advance in Wetland Classification and Wetland Landscape Classification Researches

The wetland landscape research,as a new hotspot in last 20 years,has promoted the development of the wetland science.Wetland classification on landscape scale is a complex process which integrates methodology of wetland ecology and landscape ecology.The wetland landscape classification is the basis of landscape analysis of the wetlands,which can comprehensively reflect the spatial heterogeneities and their associations with the wetland landscape,and reveal its spatial structural characteristics and functions by establishing hierarchical classification system.In this paper,the concepts of the wetland classification and wetland landscape classification were paraphrased.Advance in the researches of wetland classification and wetland landscape classification was reviewed and analyzed from domestic and abroad.The relationships between the wetland classification and wetland landscape classification were interpreted.The development trend and the problems existed on the researches of wetland landscape classification were pointed out.The classification scales were often overlooked in a given geographical condition;the wetland landscape classification,which was mainly on the basis of land use/cover,was simple.Further work is needed in classification system of the wetlands,due to lacking the classification system of the urban wetlands which is the hotspot and new area on the study of the wetlands.In future,attention should be paid to from the three aspects as shown above.
