Abstract

Abstract:

To comprehensively and systematically trace the research development trajectory in the field of nitrogen and phosphorus addition effects on soil respiration, accurately grasp the current status and frontier dynamics, and provide scientific support for future research planning and practical decision-making, this study selected the Web of Science core collection as the data source for literature retrieval, setting the search period from January 1, 2015, to December 31, 2025. Using bibliometric methods, we conducted visual analysis on 402 core publications, examining annual publication trends, journals, research institutions, author groups, keyword co-occurrence patterns, and thematic evolution, thereby constructing a high-resolution knowledge map of the field. The results showed that global annual publication growth averaged 10.6%, with a slight decline in output between 2023 and 2024, yet remaining above earlier baseline levels. The journal Soil Biology & Biochemistry ranked first in publishing related papers. ZHU Biao (with 12 publications and 982 cumulative citations) and Marie Spohn formed two highly productive and influential research groups. China led globally in both total publications (191) and citations (5999), driven primarily by large-scale networked controlled experiments. The United States and Germany produced numerous highly cited papers, establishing mainstream theoretical frameworks in the field. Keyword evolution had progressed through three stages: single-nutrient factor studies, microbial mechanism exploration, and integrated multi-system analyses. The co-occurrence strength of the keywords “phosphorus addition” and “microbial respiration” increased by 5.5 times over five years. Future research should address data gaps in tropical, permafrost, and urban greenland ecosystems, integrate high-throughput sensing technologies and multi-omics approaches, develop nonlinear models linking nitrogen-to-phosphorus ratios, microbial carbon use efficiency, and soil respiration responses, and establish a global specialized literature database to support carbon neutrality goals and accurate soil carbon stock accounting.
