海岸侵蚀与防护技术研究进展

Research Progress of Coastal Erosion and Protection Technology

全球海岸侵蚀分布广泛,给沿岸人民生产生活带来巨大损失。论文基于前人相关研究及作者在山东半岛、黄河三角洲的相关研究成果,对近年来海岸侵蚀时空变化规律及防护技术研究进行分析。结果表明,首先,海岸侵蚀是海岸动力地貌的适应性调整和再平衡过程,具有显著的空间差异性和时间非线性特征。其次,海岸侵蚀的影响因素具有显著的多样性,侵蚀机理具有显著的区域性。最后,海岸侵蚀防护与修复应关注效果的可持续性,应该在深入研究、阐明区域海岸动力地貌演变趋势的基础上,研发和应用“软式”海岸防护技术与新型海岸防护结构。

The global coastal erosion is widely distributed, bringing huge losses to the production and life of coastal people. Based on the previous researches and the author’s research results in Shandong Peninsula and Yellow River Delta,the paper analyzes the temporal and spatial variation of coastal erosion and protection technology in recent years. The results show that, firstly, coastal erosion is an adaptive adjustment and rebalancing process of coastal morphodynamics,with significant spatial differences and temporal nonlinearity. Secondly, the influencing factors of coastal erosion are significantly diverse, and the erosion mechanism is significantly regional. Finally, coastal erosion protection and restoration should focus on the sustainability of the effect. On the basis of in-depth research and elucidation of the evolution trend of regional coastal morphodynamics, “soft” coastal protection technology and new coastal protection structures should be developed and applied.
