Abstract: As an important driving force of the new round of technological revolution and management change, big data plays an important role in the process of emergency resource layout. This paper specifies the key contents and implementation process of big-data-driven emergency resource layout, including two kinds of emergency risk grid division based on historical data mining and real-time index calculation, emergency resource planning combining static layout based on administrative division and dynamical location based on spatial clustering, emergency resource demand calculation addressing demand of information accuracy and computing resource, and emergency resource reserve replenishment business processes and models. Big data technology has changed the management thinking and decision-making mode of emergency resource layout to meet the needs of emergency resource management in the data age.

Key words: Emergency resources, Big data, Risk grid, Resource planning, Demand calculation, Emergency reserve
