基于文献计量的黄河流域生态环境研究态势分析OA

Uncovering the structural patterns of evolution in hotspot research themes in a given field can deliver significant theoretical and practical value in terms of trajectories of disciplinary development and the optimiza-tion of scientific research planning.This investigation,taking eco-environmental research in the Yellow River Ba-sin of China as a case study,analyzed hotspots in eco-environmental issues in the Yellow River Basin.It em-ployed keyword analysis and social network analysis to investigate the literature from the China National Knowl-edge Infrastructure core journals and the Web of Science database(data from 2015 to 2024).The results of this study indicate the following points:(1)The research system was dominated by the Yellow River Basin theme,which,together with the policy-driven themes of eco-environment and sustainable development,constitutes the core domain,while investigation of emerging technology applications remains nascent.(2)This body of research exhibits significant spatial heterogeneity,forming three distinct regional research clusters:vegetation-soil restora-tion on the Loess Plateau,wetland-landscape,and integrated vegetation-climate-human activity governance across the entirety of the basin.(3)The literature in Chinese is primarily focused on water conservancy engineering(54.3%)and agroecology(32.1%).In contrast,the English literature demonstrates the absolute dominance of environmen-tal science(in 1800 papers)and a deep coupling with sustainable technology and water resource research.Future studies should focus on the construction of a multi-dimensional natural-economic-social coupled analytical frame-work to provide systematic decision-making support for ecological conservation and high-quality development in the Yellow River Basin.In addition,emerging technologies should be more embedded into policy evaluation pro-cesses to dynamically optimize ecological compensation standards and industrial access mechanisms.We also rec-ommend that interdisciplinary and cross-regional comparative research and data integration be strengthened to ex-plore governance pathways that are tailored to the characteristics of the Yellow River Basin.
