Bibliometrical study method on tidal freshwater marshes loss and research orientation

Many studies concerning wetland loss have been conducted in the last two decades. However, tidal freshwater marsh's research topics, mirroring hot points, vary in scientific community and change over time. A bibliometrical analysis method is demonstrated in this paper to describe tidal freshwater marsh research and changes in the research over time. For example, habitat restoration, soil composition, plantation pattern and coastal wetland have drawn increasing attention since 2005. The bibliographic methods described in this paper involved the use of 54 case studies to find critical paths regarding how tidal freshwater wetland loss has been induced by different causes. From case studies, it has been concluded that urbanization is the most important cause of tidal freshwater marsh loss. Critical paths of tidal freshwater marsh loss driving forces have been also demonstrated in this paper.
