摘　　要：海滩-沙丘系统耦合演变数学模型同时考虑近岸水沙和风沙过程,可以更好地预测砂质海岸在更大空间尺度上的地貌形态演变,为海岸带保护修复和综合管理提供依据。从概念模型、基于水沙过程的海岸地貌演变模型、海岸风沙输移模型、水沙-风沙耦合模型4个方面概述了海滩-沙丘系统耦合演变数学模型的研究进展。现有海滩-沙丘系统耦合演变数学模型可以模拟风暴作用下的海滩-沙丘侵蚀和泥沙交换、供应限制条件下的风沙输移和沙丘发育等物理过程,并初步具备多年时间尺度上的模拟能力,但在适用性、准确性和计算效率等方面仍存在不足,提出该类模型关键物理/生物过程的考虑、计算效率的提高、空间维度的拓展和实际应用的检验等今后的发展方向。Mathematical models for coupled morphological evolution of beach-dune system considering both the subaqueous and aeolian sediment transport processes can better predict the sandy coastal evolution on a larger spatial scale,providing the basis for coastal protection and the comprehensive management.This paper summarizes the research progress of beach-dune morphological models,including the conceptual models,the nearshore hydrodynamic and sediment transport models,the coastal aeolian sediment transport models,and the coupled subaqueous and aeolian sediment transport models.The state-of-the-art models can address the storm-induced beach-dune erosion and sediment exchange,as well as the supply limited aeolian sediment transport and the dune recovery on the time scale of years.They are still limited in universality,accuracy and computational efficiency.Four aspects of future research are suggested,including the consideration of key process,the improvement of computational efficiency,the expansion of spatial dimension and the test of practical application.
