摘要
海岸沙丘系统脆弱性评价揭示海岸沙丘系统脆弱性的基本特征,为海岸沙丘保护与利用提供重要依据,是海岸沙丘研究近期备受关注的一个重要方面。论文基于国内外海岸沙丘系统脆弱性评价研究相关概念、发展历程、评价指标及技术方法等的回顾,概括了其在概念内涵深化、指标体系完善、脆弱性因子辨识、技术方法发展以及评价结果应用等方面的主要进展;并针对当前概念定义难以共识、指标体系争议较大、评价方法存在局限性和理论基础略显薄弱等研究不足,提出明晰相关概念、完善指标体系、改进评价方法、强化机理研究及增强趋势研判等海岸沙丘系统脆弱性近期研究的主要方向。
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.
