【摘要】：运用系统理论观点,从数学层面上分析自然灾害系统的链式关系结构,建立自然灾害链式效应数学关系模型。通过对自然灾害结构关系模型的数学分析,揭示自然灾害系统链式响应行为的复杂性规律和运动本质,指出自然灾害复杂响应行为是外部环境复杂输入和自身内部结构关系变化两方面共同作用的结果。研究结果表明,自然灾害链式关系环是自然灾害复杂性的主要根源;链式关系环的存在使得自然灾害演化过程具有记忆性、不可逆性、自组织性、路径敏感性和间断性,以及与此相关的一切复杂现象。最后,以边坡渐进破坏失稳过程为应用分析示例说明以上研究结论的正确性。
[Abstract]:In this paper, the chain relation structure of natural disaster system is analyzed from the view of system theory, and the mathematical model of chain effect of natural disaster is established. Based on the mathematical analysis of the structural relationship model of natural disasters, the complexity and nature of chain response behavior of natural disasters are revealed. It is pointed out that the complex response behavior of natural disasters is the result of both the complex input of external environment and the change of internal structure relationship. The results show that natural disaster chain ring is the main source of natural disaster complexity, and the existence of chain relationship ring makes natural disaster evolution process with memory, irreversibility, self-organization, path sensitivity and discontinuity. And all the complications associated with it. Finally, an example of slope progressive failure instability is used to illustrate the correctness of the above conclusions.
