Research on climate change, water quality, and their relationship is critical for human survival and development. It can help better mitigate climate change and contribute to appropriate water quality management strategies under uncertain challenges in the future. In this study, bibliometric analysis was used to provide a comprehensive review of the research field of climate change and water quality from 1990 to 2022. The extraction of documents was carried out from the Web of Science Core Collection database. VOSviewer, Bibliometrix R-package, and CiteSpace were used for analysis and scientific mapping. The results show that China, the United States, and Canada are the main countries driving this field, and China and the United States closely cooperate. It was also found that the areas of water eutrophication and climate change research had a close relationship and were the current research hotspots. Finally, it is revealed that the areas of sustainable development of climate change and water quality management, model simulation and method improvement between climate change and water quality, groundwater quality risk assessment driven by climate change, the impact of water on climate change, and expanding the research scale of the relationship between climate change and water quality will be the future research trends in this field.

[Display omitted] • This is nearly 40 years of time field monitoring of changes in the distribution of Siberian cranes at staging stopover sites in the Momoge Reserve. • The spatial distribution of Siberian cranes at staging grounds under human and climatic disturbances migrates in response to spatial changes in the water body. • Siberian cranes are more sensitive to changes in water fragmentation at staging areas. • Neither too fragmented nor too aggregated water bodies are suitable migratory resting habitat features for Siberian cranes. The Siberian crane (Grus leucogeranus), a critically endangered species, is used as an indicator species for ecosystem stability because of its sensitivity to the environment. The distribution of Siberian cranes has shown dramatic fluctuations on an order of magnitude at the main stopover site (Jilin Momoge National Nature Reserve) since the present century, which poses a great challenge to the conservation of endangered species. Research on the threshold values of key factors of the Siberian crane in stopover habitats and the relationship between the Siberian crane and hydrological temporal and spatial fluctuations can promote endangered species conservation. The response of population changes and distribution patterns of Siberian cranes to hydrological temporal and spatial patterns of wetlands was analyzed from 1984 to 2020. The results showed that population changes and distribution patterns of Siberian cranes were highly correlated with hydrological temporal and spatial patterns in the study area, and their variation trend was the same. However, there were obvious stage migration changes in the core activity area of the Siberian crane (1984–2000, 2001–2010 and 2010–2020). The habitat characteristics of fragmentation, dispersion and complex shape of water bodies changed from steady to dramatic fluctuations and then leveled off in the core activity area of Siberian cranes during the 37 years of migration transit. This was closely related to the early agricultural reclamation and the later ecological water replenishment project in the study area. In addition, the trend of the water pattern index of the spatial distribution of Siberian crane active habitat was also closely related to their habitat selection preference. When the perimeter area fractal dimension of water (1.27–1.40), landscape division index (0.73–0.95) and aggregation index (80.97–91.36) are within a certain stable threshold, the stopover habitat of the Siberian crane is suitable. This study will provide scientific guidance for the conservation of the Siberian crane population and the development of wetland restoration projects. [ABSTRACT FROM AUTHOR]
