Living estuarine shorelines as nature-based green engineering for coastal stabilization: A scientometric analysis

Abstract

Natural estuarine wetland shorelines play a crucial role in coastal stabilization and preserving ecological security patterns. The effectiveness of estuarine shoreline engineering in reducing coastal erosion and maintaining the stability of ecosystem structures and functions is tightly linked to their types and structures. Although the living estuarine shorelines have received increasing attention, there have been few systematic literature reviews on the development process, research hotspots and future trends in this field. Here we summarized the literatures, and analyzed them in terms of annual publications, subject categories, co-cited journals, countries, institutions, authors, references, and keywords based on OriginPro, VOSviewer, and CiteSpace softwares. Results showed that the studies on living estuarine shorelines have experienced a rapid development phase since 2004, which is mainly categorized into Environmental Sciences and Oceanography, and the research institutions and scholars are mainly from the USA and China. The effects of human activities and climate change on the structures and functions of estuarine ecosystems are the dominant topics. Furthermore, the nature-based management solutions have been proposed to improve the functions and services of estuarine ecosystems. Currently, the habitats of estuarine wetlands worldwide have undergone varying degrees of degradation, therefore, the ecological conservation and restoration of estuarine shorelines urgently require the active participation of the public. It is highly important to integrate multi-disciplinary and multi-technology approaches to construct nature-based, more resilient, multi-service synergistic, and composite living shorelines in coastal zones. The findings of this research can provide scientific guidelines for the adaptive management and conservation of estuarine wetlands.
