The application relates to a cross-modal generative satellite-ground network semantic communication method with super-high compression rate, which comprises the following steps: S1, establishing a generative cross-modal satellite-ground network semantic communication system; S2, establishing a satellite-ground network semantic communication system model fusing NOMA technology; S3, establishing a dynamic switching algorithm; S4, establishing a double-state satellite-ground link simulation model: considering the influence of the multipath, shadow and Doppler factors existing in satellite-ground communication, dividing the satellite-ground transmission link into two states of good and bad, modeling the channel characteristics by using Rician and Rayleigh distribution, and simulating the Doppler frequency shift through Doppler phase rotation, and completing satellite-ground channel modeling and simulation. In the single-user scene, the original image information is efficiently compressed into a compact text semantic representation through the cross-modal semantic compression module, an end-to-end generative model is adopted to guarantee high semantic consistency and robust reconstruction, the data volume is greatly compressed, and low-delay semantic transmission is achieved, so that the bandwidth burden of the satellite-ground network is effectively reduced.

This invention discloses a system and method for constructing earthquake-themed scenarios based on multi-source 3D GIS data, belonging to the field of 3D geographic information system technology. It aims to solve the technical problems of data silos, limited information display, delayed data updates, and lack of end-to-end connectivity in earthquake emergency response. The system adopts a layered architecture consisting of a data resource layer, a data fusion layer, a service support layer, and an application display layer. The method involves building a basic 3D GIS emergency scenario, aggregating multi-source earthquake data, achieving spatiotemporal data fusion and event correlation, and completing integrated 3D display and decision support. This enables unified spatiotemporal fusion and real-time dynamic updates of earthquake data across all dimensions, as well as 3D visualization and spatiotemporal simulation of the entire pre-earthquake, during-earthquake, and post-earthquake chain. This provides global and three-dimensional decision support for earthquake emergency command, significantly improving the efficiency, accuracy, and systematic nature of earthquake emergency response.
