Abstract:Mangrove plays an essential role in preventing against tropical cyclones and attenuating wave energy, promoting sedimentation and protecting beach, stabilizing coast and safeguarding banks and so on, which is an important natural defense against natural hazards such as tropical cyclones, storm surge and coastal erosion. Tropical cyclone is one of the largest natural threats to mangroves which can impair ecosystem functions such as resisting natural hazards and maintaining biodiversity. Although increasing attentions have been paid to the effects of tropical cyclones on mangroves globally, there is a lack of systematic analysis and review on research progress in this field. In this study, using the core set database of Web of Science as the data source, CiteSpace was applied to conduct the bibliometric analysis and visualization mapping for the studies on the effects of tropical cyclones on mangroves during 1995—2021, in order to clarify the research status, trends and hot spots, and reveal the future development direction. The results indicate that: (1) the annual number of the published papers in this field has fluctuated and increased over time, especially after 2013, indicating studies in this filed have received an increasing attention; (2) Countries such as United States, Australia and India are taking the lead in this research field, and United States is characterized with the highest intermediary centrality and followed by Germany, where United States has extensive and close cooperation with Germany, France, Japan and other countries; (3) Florida in the United States, the Caribbean, northern Australia and southern India are hot spot areas; (4) Research hotspots have been developing over time, from the disturbance and damage on mangrove vegetation to the impact on functions such as carbon sequestration and storage, coastal protection. Increasing attention has been paid to the impact of tropical cyclones on mangroves in the context of global change, mangroves’ resilience to disturbance from tropical cyclone, and the model simulation based on remote sensing and big data processing. At present, the effects of tropical cyclones on mangroves is still in a period of rapid development. The important directions of future research include quantifying the effects of tropical cyclones on ecological functions of mangroves, exploring the interaction between tropical cyclones and sea level rise and its impact on mangroves, constructing a complete data set of observation system, and so on. This study provides a quantitative and visual analysis of the long-term research progress on the impact of tropical cyclones on mangroves, which can provide the reference information for forecasting the impact and risk of tropical cyclones on mangroves, and mitigating and addressing the risks.
