Abstract:

To address the construction of China's independent knowledge system in safety science, this study employed literature analysis and theoretical construction methods to interpret the connotation and development context of the discipline system, refined the theoretical accumulation and paradigm evolution of the academic system, and analyzed the generation logic and hierarchical structure of the discourse system. The results indicate that the discipline system exhibits interdisciplinary characteristics, evolving through four stages—embryonic exploration, initial establishment, rapid development, and cross-disciplinary innovation—forming a full-chain spectrum of source-prevention-control-rescue-management. The academic system is rooted in the organic unity of theory and practice, with paradigm shifts from passive response to proactive prevention, and from human-physical defense to intelligent protection. It features vertical coherence, horizontal integration and dynamic evolution. The discourse system follows cultural, theoretical, and practical generation logic, forming a four-tier structure of value, theory, institution, and practice, with effective integration between local leading theories and international academic expression. Based on the above analysis, the construction path of the independent knowledge system is proposed from the knowledge, practice and subject dimensions. The discipline system provides comprehensive planar support, the academic system runs through the theoretical mainline, and the discourse system forms subject-oriented communication carriers. The three parts complement each other in a point-line-plane structure and jointly build the three-dimensional architecture of China's independent knowledge system of safety science.
