摘要： 从自然灾害系统的观点出发,阐述了自然灾害系统的特点,提出了自然灾害复杂性的概念。基于前人研究的一些成果,讨论了分形、混沌、人工神经网络等非线性理论以及定性与定量综合集成技术在自然灾害复杂性研究中的应用。自然灾害复杂性的研究可以促进人类对自然灾害整体行为的探索。

Abstract: From the view point of system of natural disasters, some features of this system are described, a new concept of the complexity of natural disasters is put forward. On the basis of some research achievements in natural disasters, the application of fractal dimension and chaos, artificial neural network,as well as the comprehensive technology with qualitative and quantitative integration to the study on the complexity of natural disasters are discussed. Through the study on the complexity of natural disasters, the process of investigation on the whole behaviour of natural disasters will get a promotion.
