The article construct the emergency management technology. Support capacity evaluation index system, using AHP method and fuzzy gray comprehensive evaluation method to conduct qualitative and quantitative evaluation of emergency management technology support capacity. From the evaluation results, it can be seen that the overall emergency management support system's capability is at a moderately high level, close to the "higher" level, but there is still a long way to go according to the high level. Among the indicators at the decision-making level, the proportion of science and technology support capacity in the processing phase and the rehabilitation and rehabilitation phase are very large, respectively 65.5% and 29.7%; the proportion of science and technology support capacity in the preventive preparation phase is relatively small. Among the second-level indicators, the larger proportion has the technology support capabilities of risk prevention and monitoring, the technology support capabilities of risk diagnosis and early warning, the technology support capabilities of decision-making and command, the technology support capabilities of information resource integration, the technology support capabilities of loss assessment and processing, and the restoration and reconstruction of technology support. ability.
