Abstract
Wetland landscape ecological study is a rising research field for wetland study, which is based on landscape ecology.Remote sensing(RS) and Geographic Information System(GIS) have been widely used in wetland research in recent years.The advance of the two techniques has been providing new method and technical support for wetland landscape ecological study.On the basis of correlative research literatures in recent years,this paper respectively evaluated the application of RS and GIS techniques in wetland landscape ecological study.Four research areas were discussed for the application of RS,included: landscape pattern study,landscape function study,landscape dynamic study,landscape scale study.The application of GIS was summarized from four aspects as follow: assisted for landscape classification,landscape mapping and landscape index statistic,landscape dynamic information acquirement and analysis,landscape programming and management.In this paper,the advantages of using the two techniques in wetland landscape ecological study were analyzed,the problems existed at present were also discussed.The prospect of the application of RS and GIS in wetland landscape ecological study was brought forward at the end of the paper.
