Abstract:

To build a operational technological system of information service for comprehensive risk prevention of natural disasters is an inevitable requirement to support disaster prevention, mitigation and relief in the new era. Aiming to the demand for comprehensive risk prevention information service of the whole chain, multi-agent and multi disaster, this paper establishes the technical system framework of comprehensive risk prevention information service of natural disasters. We construct the comprehensive risk prevention information service product system covering the whole process of normal disaster reduction and abnormal disaster relief (such as, pre disaster prevention, in disaster rescue, post disaster recovery and reconstruction) and breaks through four key technologies, including the information product development, industry data collaboration, network big data mining Information and service platform integration. In terms of information product development, we have developed disaster information product production, expression and dynamic customization technology based on three standard disaster information elements: disaster causing, disaster situation and disaster relief. In the aspect of industry data collaboration, we have developed a new mechanism of two-way adaptive departmental micro service data sharing and multi-department and multi-source heterogeneous data access and fusion processing technology. In the field of network big data mining, we have developed information mining and fusion analysis technology of disaster causing, disaster situation and disaster relief elements based on Web pages, mobile communications, social networks, Internet of things and other network big data. For building information service integration platform, we have developed spatiotemporal distributed big data management, business tool model integration and "cloud + end" multi-channel information service technology based on cloud service architecture. The technical system solves the problems of low timeliness and insufficient completeness of disaster information services, and provides technical support for opening up a second way to obtain disaster information data distinguished from government statistics.

Key words: natural disasters, comprehensive risk prevention, data collaboration, network big data, information service and information platform
