Wetland research in landscape ecology, as a new hot field in recent years, has resulted in the development of wetland science. However, wetland research on landscape scale is a complex process which integrates wetland ecology with landscape methodology. So some problems have emerged in the development of wetland in landscape research, and significantly blocked the progress for wetland research in advance. This paper elaborates the current situation and problems in landscape studies on wetlands, and discusses future of wetland research in landscape ecology. We believe that wetland research into landscape ecology is still the main field in conservation and rational utilization of wetlands. Especially, we have obtained latest conclusions in landscape structure and pattern, process and function, evaluation and management of wetlands. But some new problems are increasingly emerged, including the concept of wetland landscape, classification, precision of information of wetlands from remote sensing imagine, application of multi-scale data, methodology of structure and pattern and scale choice for process and function of wetlands. How can we solve these problems, and how can we apply the theory of landscape ecology to the practice of wetland research? In future, five aspects are to be addressed: (1) to focus attention on wetland classification system with special ecological characteristics and distribution features in a given geographical condition; (2) to strengthen studies on landscape fragmentation of wetlands to exhibit changes in landscape patterns of wetlands impacted by human activities; (3) to develop new methodology for landscape patterns by integrating ecological process and functions of wetlands; (4) to conduct multi-scale biodiversity of wetlands study to exhibit maintaining capacity of wetland landscape in different patch-corridor-metrics models influenced by natural or human activities in a given region; and (5) to place emphasis on landscape management research in applying principles of pattern-process-function for conservation, planning and design of wetlands.
