Abstract: 【Purpose/significance】In the face of extremely complex and systematic natural disaster emergency management, the impor⁃tant value of knowledge is increasingly prominent. A holistic analysis paradigm of knowledge management integrating structural ele⁃ments and evolution process can form theoretical inspiration or practical guidance for specific emergency management activities. This paper attempts to explore a systematic understanding of the interdisciplinary research field of emergency knowledge management.【Method/process】In this paper, data such as news reports, government documents, official websites, individual comments and aca⁃demic literature about flood mitigation management activities in Kemaman, Malaysia during 2013-2014 were obtained from multiple channels. Based on the grounded theory, these data were coded and analyzed by exploratory case study method.【Result/conclusion】
This paper constructs an element and process framework of emergency knowledge management for natural disasters, including emer⁃gency knowledge acquisition, knowledge integration, knowledge sharing, emergency coordination, emergency knowledge application and emergency knowledge innovation six elements, these elements in the different stages of emergency management and application value of different operation process【. Innovation/limitation】This paper expands the research boundary of Library and Information Sci⁃ence from the perspective of Knowledge Science, and enriches the theoretical system of emergency knowledge management. Due to the limitations of general applicability of case study, it is necessary to find more extensive data support.
