海岸带地质灾害评估理论与方法研究进展

Overviews on theory and approaches of coastal geological hazards evaluation

摘要: 文章在总结前人关于地质灾害分类的基础上,重新探讨了海岸带地质灾害的涵义;论述与地质灾害评估相关的几个概念,并从性质分类上总结了海岸带地质灾害脆弱性、危险性、易损性、风险性评估的理论和方法;针对目前海岸带地质灾害评估存在的问题,认为未来海岸带地质灾害评估研究需要从研究海岸带地质灾害特殊性入手,采用多学科交叉的方法综合研究,以实现海岸带地质灾害评估定量化和管理空间化。

Abstract: Based on the previous studies of the classification of geological hazards,the concept of coastal geological hazards is re-examined.After introducing several concepts related to geological hazard evaluation,the theories and various methods about the frangibility,hazard,vulnerability and risk evaluation of coastal geological hazards have been summarized.In addition,it is suggested that the interdisciplinary methods need to be used in the quantitative evaluation and information-based management of coastal geological hazard in the future.
