本文对孕灾环境、致灾因子、承灾体和灾情给予了定量研究,建立了自然灾害系统模型。该模型不但为灾情计算提供了一个统一的标准,而且对成灾的因果关系表述得十分清楚。它是一个综合性强和操作简单的实用模型,也使灾情评估和成灾机制得到统一。
This paper gives a quantitative study of the pregnant environment, disaster-causing factors, disaster-bearing bodies and disasters, and establishes a natural disaster system model. The model not only provides a unified standard for disaster calculation, but also makes it clear that the causal relationship between disaster and disaster is very clear. It is a comprehensive and easy-to-use practical model that also enables disaster assessment and disaster recovery mechanisms to be unified.
