An analysis and visualization of global wetlands based on scientmetric from 2002 to 2022

Abstract

Recent studies have focused on wetlands as they can benefit humans in terms of spiritual satisfaction and mental health. This paper evaluated the scientometric analysis of 2,388 studies published on the Web of Science between 2002 and 2022. It identified hotspots and trends in wetland research using VOS viewer, Origin, and Citespace software. Analyzing global wetland research publications shows a clear upward trend. Moreover, researchers in the United States, the People's Republic of China, Australia, Canada, and India devote considerable attention to wetland research. Network keyword co-occurrence analysis showed that wetland research covers constructed wetlands, climate change, wastewater treatment, phytoremediation, restoration, and hydrology. Furthermore, the United States is the world's main hotspot for wetland research; China, Canada, Australia, and others are behind. Due to the growing appreciation of wetlands' importance, wetland research will receive more attention from researchers around the globe. Additionally, wetland tourism articles should have improved quality since most publications are rarely cited. This paper presents an overview of the scientometric methodology for global wetlands research. Additionally, scholars working on wetlands can use scientometric analysis meaningfully and effectively for their future research.
