摘要
灾害链是在时间上有先后、空间上彼此相依、成因上相互关联,破坏性极强的呈链式结构的多种灾害。由于灾害链的形成与演化具有叠加、放大和链式效应,已经成为灾害研究的热点和难点。受全球气候变化和人为因素的双重影响,海岸带地区成为地球上最活跃、最脆弱的区域。海水入侵和土壤盐渍化成为海岸带地区面临的主要地质灾害,威胁生态安全和人类生存环境,这2种灾害相继发生、相互关联,构成海水入侵-土壤盐渍化灾害链。归纳总结了灾害链研究进展,阐述了海水入侵-土壤盐渍化灾害链的演化特征和研究中的关键科学问题,展望了海水入侵-土壤盐渍化灾害链研究趋势。
The disaster chain is a highly destructive chain structure, including a variety of disasters that are sequential, spatially dependent, related genetically to each other. Due to the superposition, amplification and chain effect during the period of the formation and evolution of the disaster chain, it is one of hotspot and difficult points in disaster research. Affected by global climate change and human factors, the coastal zone is the most active and vulnerable region on the Earth. Seawater intrusion, together with soil salinization, have become the main geological disasters in the coastal zone, threatening ecological security and human living environment. These two types of disasters have sequentially occurred and are related to each other, forming a seawater intrusion-soil salinization disaster chain. Finally, this study summarizes the research progress of the disaster chain, indicates the evolution characteristics of the disaster chain and the key scientific problems, and forecasts the research trend of the disaster chain.
