Abstract:

As an important aspect of coastal dune system research, the vulnerability assessment of coastal dune systems not only reveals the basic characteristics of the vulnerability of coastal dune systems, but also provides some references for the protection and utilization of coastal dunes, and has received extensive attention recently. Based on the review of relevant concepts, development process, evaluation indicator system, and technical methods of the vulnerability assessment of coastal dune systems in China and internationally, this article summarized the main progress in deepening the concept connotation, improving the evaluation indicator system, identifying vulnerability factors, optimizing technical methods, and applying assessment results. It also identified that there are still some deficiencies in the current research, such as the lack of consensus on the definition of concepts, controversy in developing the indicator system, limitations in the assessment methods, and the lack of very strong theoretical basis. Therefore, the research of vulnerability assessment of coastal dune systems in the future should focus on clarifying the concept of vulnerability of coastal dune systems, improving the indicator system and assessment methods, strengthening the mechanism research, and predicting the development trend of vulnerability.

Key words: coastal dune systems, vulnerability, assessment, progress, prospect
