Research progress of habitat network from the perspective of migratory bird protection in recent ten years

Migratory birds are the most indicative taxa of terrestrial biodiversity and are highly sensitive to ecology. However, due to the continuous acceleration of urbanisation, the loss of habitats for a large number of migratory birds has seriously threatened their survival. Therefore, it is particularly important to build a habitat network aiming at the protection of migratory bird habitat. Using VOSviewer 1.6.20 and Bibliometrix, relevant studies at home and abroad from 2013 to 2023 were metrologically analysed, and the keyword co-occurrence knowledge map was compared to sort out the high-frequency keywords and analyse the different hot trends of the current habitat network-related studies under the perspective of migratory bird conservation. The results showed that: (1) The relevant research could be summarized into four hot trends, including research on the construction and optimization of migratory bird habitat network, migratory bird protection and adaptive mechanism, migratory bird habitat protection and management, and migratory bird monitoring and assessment system. (2) Although the study of European and American countries was dominant at present, China was still one of the hotspot countries, and Poyang Lake and Yellow Sea were also hot research areas with natural advantages and great research potentials. (3) Richard A. Fuller, Theunis Piersma, etc. were the core scholars in this research field, and there were many articles published in Biological Conservation journals. The School of Biological Sciences of the University of Queensland, Global Flight Network (GFN), etc. were the main forces in this research. (4) Based on the perspective of migratory bird conservation, it is proposed that the ‘multi-scale coupling’ and ‘multi-perspective joint’ approach can be used to connect the current national land planning scheme, and the three-span cooperation approach can make up for the shortcomings of the existing methodology to adapt to the different land uses in the future, which may be the focus of the future research.
