英文摘要：

[ Purpose/significance ] Existing emergency early-warning researches are launched respectively from theory and practice. The results of these studies help our government to monitor and identify the occurrence of emergency, predict the impact it may bring, and provide detailed references for taking quick and effective measures. [ Method/process ] By investigating relative lit- erature, this paper has combed the emergency early-warning work flow, summarized the research achievements of related methods in every link of the work flow, and briefly introduced some existing emergency early-warning models and systems. [ Result/conclu- sion ] With the hope to provide comparison and historical references for researches on emergency early-warning, the paper summari- zes the focuses and shortcomings of the existing emergency early-warning studies, and points out the directions for further research.
