The wetland landscape pattern research has been one of the key research fields of landscape ecology and Global Changes. 3S technology and modeling methods have been applied widely and proved to be important approaches in wetland landscape researches, Based on researches of 3S and model methods in wetland landscape pattern, this paper reviews the following research methods such as the RS imagery data selection and classification, the measurement of wetlands' basic data and parameters, the landscape index and dynamic models' application in quantitative analysis of wetland landscape patterns and changes. Several key problems including the increase of classification and cartography precision, application and improvement of dynamic models are also emphasized in this paper.
