Case Database Construction and Temporal-spatial Analysis of Mass Incidents in China Based on GIS

As one of the important research areas of public safety and sociology, the study of mass incidents is inseparable from the support of a large number of real cases data. However, there is a lack of available and reliable mass incidents databases in academic circles in China. Using the news retrieval approach, this paper builds a case database of mass incidents in China from 1998 to 2014 based on the GIS system. Then the spatial-temporal distribution rules of these mass incidents data are analyzed from the perspective of geography. Our research effectively integrates the temporal attributes, spatial attributes, organizational attributes and violence attributes of mass incidents. The results show the hot areas and temporal distribution of mass incidents and mass violence, and reveals the main triggers of these events.
