摘要
可视化灾害数字仿真重构理论研究,不仅可以实现对灾害空间数据进行有效的集成管理和时空分析,而且为灾害的防治、应急管理和工程论证等提供可靠的依据,是解决灾害实验的危险性和不可重复性的最佳途径。本文在综述灾害防治手段及相关研究进展的基础上,明确了灾害的定义和特征,论述了灾害的分类与分级方法,研究了孕灾环境、承灾体和致灾因子的成灾模式,提出了灾害空间的涵义。在灾害本质解析的基础上,提出灾害数字仿真重构理论的概念,并论证了理论的可行性,为进一步的研究创造了条件。
Theory of visualization-based disaster digital simulation reconstruction is helpful not only to management and analysis of disaster spatial data, but also to providing reliable proof for disaster reduction, emergency management and engineer demonstration, which is the best solution to solve the fatalness and non-repeatability of disaster experiment. Based on the overview of disaster reduction measures and relevant study, the paper proposes the definition and attribute of disaster, discusses the method of classifying and grading disasters, investigates disaster environment and disaster pattern and gives a concept of disaster space. On the basis of parsing disaster nature, the paper presents the concept of visualization-based disaster digital simulation reconstruction theory, and analyzes its feasibility, which will set solid foundation for further study.
