Abstract:

The phenomenon of drought disaster chain caused by drought disaster and its secondary disasters has a great impact on natural environment, society, economy and so on. In order to review the current research of drought disaster chain, different definitions of drought disaster chain and its two development stages have been retrospected. Then the main contents of drought disaster chain has been summarized, including the classification of drought disaster chain, evolution mechanism and control measures. Moreover, the main research methods involved in the current research have also been reviewed, including qualitative analysis, correlation analysis, probability model based method, complex network based method, and so on. From the goal of building systematic disaster prevention and mitigation, the problems existing in the current research were finally identified. The top-level research design and quantitative results are still needed. In the future, with the support of multidisciplinary knowledge, we should establish the chain catastrophe theory and put forward a series of quantitative methods. The research of this paper will be helpful to systematically understand the current progress, key points and difficulties in drought disaster chain studies, and also provide some references for future research.

Key words: drought, disaster chain, chain effect, disaster system

摘要:

长期以来,干旱灾害及其多样化的次生灾害形成了干旱灾害链现象,对人类社会经济产生了广泛的负面影响。为系统性剖析当前干旱灾害链的研究进展,首先回顾了干旱灾害链的不同定义和两个发展阶段,概述了干旱灾害链的主要研究内容,包括干旱灾害链的演化、分类、链式传递机理和减灾防治措施。重点梳理了干旱灾害链研究中的主要方法,包括定性分析方法、相关分析方法、基于概率模型的方法、基于复杂网络的方法等。最后从构建系统性防灾减灾工作的目标出发,指出当前干旱灾害链研究仍缺乏系统的顶层设计和定量化成果,未来应在多学科知识的支撑下,突破链式灾变的理论,创建定量化的研究方法体系。该研究成果有助于系统性理解当前干旱灾害链的研究进展、重点和难点,并为后续研究提供一定借鉴。
