| In response to four major technical problems of traditional flood evacuation technologies:inade-quate ability to identify flood risks dynamically, backward methods of identification, tracking and early warning of threatened groups, inefficient optimization techniques for real-time flood disaster evacuation paths, and lack of emergency risk evacuation decision support platform, this article integrated multi-source information such as satellite remote sensing, GIS, unmanned aerial vehicles drone photography, and used technical means such as numerical simulation, multi-source LBS, big data, electronic fence and real-time communication, and put forward rapid over-standard flood risk modeling and judging technique to adapt to different scattering,overflowing and breaching scenarios,accurate identification,rapid early warning and re-al-time monitoring technology of threatened groups, and a real-time dynamic optimization technology for the transfer route of population evacuation. On this basis,a flood control emergency evacuation decision sup-port platform based on multi-source information of sky, space, earth and water and real-time information driven was developed. The functions such as information recognition of emergency evacuation to the crowd, the intelligent management of the evacuation elements, and the whole process of evaluation of the transfer effect were developed. The research results were simulated and applied in the Jingjiang flood diversion area in the Yangtze River Basin. |
