Applications of models in lake salinization research: Current status and prospects

Abstract

[Objective] Lake salinization has become increasingly severe due to global climate change and human activities,posing significant threats to ecosystems and water resources. The aims are to evaluate the current status of model research on lake salinization and summarize research directions. [Methods] Bibliometric tool VOSviewer was employed, with Web of Science Core Collection database serving as the data source, to conduct a quantitative analysis of publications in the field of lake salinization and model research spanning from 1900 to present. [Results] The result showed that the bibliometric visualization exhibited distinct phased changes. The research domain showed interdisciplinary characteristics across multiple directions. Key research hotspots were systematically summarized, and future trends were projected based on keyword burst detection analysis. The results demonstrated that the field went through three developmental phases: a slow exploration phase, a stable development phase, and a rapid growth phase. Since 2009, influenced by heightened interest in climate change research, the volume of publications surged with sustained increases projected for the future. Research hotspots included ecosystem dynamics, environmental variation, and hydrological modeling. Keyword burst analysis highlighted a transition toward integrated research, with interdisciplinary knowledge synthesis and methodological integration becoming increasingly crucial. Future research is anticipated to focus on salinization in high-altitude and arid regions(e. g., Qinghai-Xizang Plateau and Xinjiang). Cutting-edge technologies such as remote sensing and machine learning are expected to be widely applied for salinity dynamics analysis and water resource management, thereby promoting advancements in this field. [Conclusion] Current research status of this field across hydrological, geological, and ecological disciplines is comprehensively reviewed, with research hotspots and emerging trends identified, providing a scientific foundation for ecological conservation and sustainable water resource utilization in lakes.
