Research progress of China’s grassland ecosystems in the 21st century based on bibliometric analysis
Grasslands are critical ecological barriers and carbon sinks, and research on China’s grassland ecosystems has expanded in response to climate change, ecological restoration, and carbon-neutrality goals. This study conducted a systematic bibliometric analysis of the research progress of China’s grassland ecosystems from 2000 to 2025. The results show that publication output increased slowly before 2020 and then rose exponentially thereafter. A total of 18 countries and regions participated in this field, with China ranking first, followed by the United States. Keyword co-occurrence analysis identified five thematic clusters, from which three major evolutionary research trajectories were further distilled: (i) driver attribution and remote-sensing diagnosis; (ii) carbon cycling and the re-evaluation of “vegetation– soil–microbe” mechanisms; and (iii) ecosystem services and spatial governance. The study further identifies that the field continues to face several challenges, including weak integration of cross-scale and multi-process analyses, insufficient mechanistic interpretation, limited quantification of uncertainty, and obstacles in translating research outcomes into policy. Overall, the findings indicate that, supported by multi-source data fusion, research on China’s grassland ecosystems is shifting from change monitoring and attribution toward mechanistic explanations of stability and responses to extreme events. In addition, workflows such as Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) and Patch-generating Land Use Simulation (PLUS) show considerable potential for incorporating carbon sequestration and ecosystem service assessments into verifiable scenario comparisons and spatial governance decision-making.
