近20a来我国地质灾害链研究综述

ON GEOLOGICAL HAZARD CHAIN RESEARCH IN CHINA IN RECENT 20 YEARS

作为生活和工程中常见的一种灾害形式,地质灾害具有突发性和广泛性等特点,应用灾害链理论对其进行研究已成为当前地质灾害研究领域的重要方向。为了解近年来我国地质灾害链的研究进展,采用文献分析法对近20a(2002~2021年)相关研究文献进行检索,结果表明现阶段地质灾害链研究内容侧重于地震、滑坡、泥石流和降雨灾害链,形式多为对历史已发生地质灾害链的统计分析,有关地质灾害链的研究方法和风险评价仍有待完善。最后,根据文献分析结果及当前灾害链发展现状,对地质灾害链的未来发展进行了展望。

As a common form of disasters in life and engineering,geological disasters have the characteristics of sudden occurrence and extensive,and the application of disaster chain theory has become an important direction in the research field of geological disasters.To master the progress of geological disaster chain in China in recent years,this paper adopts literature analysis method for nearly 20 years(2002~2021),relevant research literature retrieval,the results show that the present geological disaster chain research content focused on earthquake,landslide,debris flow and rainfall disaster chain,form is the history there have been more statistical analysis of geological disaster chain,The research methods and risk assessment of geological hazard chain need to be improved.Finally,according to the literature analysis results and the current development status of the disaster chain,the future development of the geological disaster chain is prospected.
