Theory of Visualization-Based Disaster Digital Simulation Reconstruction and Case Study T(II):--Theoretical Framework and Conceptual Paradigm

Theory of Visualization-Based Disaster Digital Simulation Reconstruction is helpful not only to managing and analyzing disaster spatial data, but also to providing reliable proof for disaster reduction, emergency management and engineer demonstration, which is the best solution to the fatalness and non-repeatability of disaster experiment. The paper presents the concept, technical support, feasibility and content of Theory of Visualization-Based Disaster Digital Simulation Reconstruction. The operation flow of disaster digital simulation theory, and the principles and procedure of establishing disaster digital model are proposed. The conceptual paradigm of disaster digital simulation model is established by analyzing the action mechanism and function process between hazard factor and hazard bearing body, together with structural change of hazard bearing body. On the basis of the work above, the whole theoretical system of Theory of Visualization-Based Disaster Digital Simulation Reconstruction is constructed.
