Abstract:In order to promote the research and development of science of safety science popularization, and this in turn enhances the practice effects of safety science popularization, aiming at the status quo of the lack of theoretical research on safety science popularization in the current academic, the establishment of science of safety science popularization was researched based on the discipline construction. First of all, from the perspective of safety science, the definition of safety sceince popularization was proposed based on the definitions of sceince popularization. And then, the definition of science of safety science popularization was put forward, and its connotation was analyzed thoroughly. Finally, five basic issues in science of safety science popularization (including research scope, discipline features, research object, research content and research purpose) were systematically discussed. The results show that science of safety science popularization is a new interdisciplinary nterdiscipline which specialized in studying the laws of safety science popularization, and its researches can provide the diagnostic informations necessary forimportant theoretical basis and scientific evidence for the practice of safety science popularization.
