Bibliometrics study on coastal wetland ecosystem restoration and its application of remote sensing technology
Coastal wetl ands play an important role in the health of local,regional and global ecosystems through climate change mitigation and biodiversity conservation.As a result of human activities,climate change and invasive alien species,coastal wetland ecosystems in some areas of China are facing a crisis of impaired ecosystem functions and declining biodiversity.Remote sensing technology has been widely used in the restoration of coastal wetland ecosystems over the past 30 years because of its unique advantages such as wide observation range,fast access to information,large amount of information and high comparability of information.This work presents a visual analysis of the literature on the application of remote sensing technology in coastal wetland restoration based on bibliometrics.Our analysis shows that the application of remote sensing technology in coastal wetland ecology originated in 1993 and entered a period of rapid development until 2008,with a significant increase in the number of publications in the last three years.In 2010,China surpassed the US for the first time in the field of coastal wetland remote sensing technology,jumping to the first place.Among the major research institutions,the Chinese Academy of Sciences had the highest number of publications,followed by the US Geological Survey and East China Normal University.Keyword clustering analysis shows that research on coastal wetland ecosystem evolution,drivers and restoration,coastal marsh wetland ecology,water body information inversion,vegetation parameter inversion and remote sensing technology are the main research hotspots at present.In the future,China should further strengthen the research on the response and adaptation of coastal wetland ecosystems in the context of global climate change,and reveal the differences in response and adaptation of coastal wetlands at different temporal and spatial scales.At the same time,in the face of increasingly severe challenges such as climate change,we should respond flexibly to local pressures and develop relevant policies for local monitoring and feedback related to management actions.Establish a coastal wetland monitoring network to regularly collect and analyse data,and use big data and decision-making tools to quickly make corrections to plans.
