Abstract: 【Purpose/significance】At present, China is in a critical period of development and transformation, and a high degree of un⁃certainty has emerged with the rapid development of society.【Method/process】This paper summarizes the research status of crisis in⁃formation demand forecasting at home and abroad, introducing the disaster chain theory into the research of crisis information demand forecasting for the first time. The first part gives an overview of the relevant contents of disaster chain and crisis information demand and expounds the feasibility of applying disaster chain theory to crisis information demand prediction; then, focuses on discussing a method of crisis information demand prediction based on disaster chain theory and discusses the framework and application problems
of this method in detail; next, applies this method to the rescue information demand of disaster-stricken people in the "6.24" landslide in Maoxian County, Sichuan Province; finally, the forecasting performance of four forecasting methods for crisis information demand is compared.【Result/conclusion】This paper aims to enrich the theoretical framework of crisis information demand forecasting and ex⁃pand the application scope of disaster chain theory in disaster field. Ultimately achieve the goal of providing basis for government emergency information management decision-making.【Innovation/limitation】This paper proposes a crisis information demand fore⁃casting method based on disaster chain theory, which enriches the theoretical research framework of crisis information demand fore⁃casting. Due to the great difficulty in obtaining data, it is difficult to compare the obtained prediction results with the actual informa⁃tion demand of June 24 Maoxian landslide to test the validity of the method. This prediction method still needs more theoretical and
practical tests.
