摘要:
海岸侵蚀是沿海各国面临的共同问题,海滩养护是当前砂质海岸保护的最佳手段,在全球范围内得到广泛应用。本文回顾了海滩养护技术的发展历程,总结了世界范围的海滩养护实践,分析各国海滩养护理念上存在的差异。以研究文献为基础,总结归纳了平面和横向剖面的补砂方式、辅助工程技术和海滩模型预测等方面的海滩养护技术研究进展,并在此基础上提出了海滩养护的未来发展趋势:①针对复杂海岸的海滩养护应用拓展; ②基于沉积物管理的海滩养护修复; ③从地貌系统到生态系统全面考虑的海滩养护技术; ④全球砂源赤字条件下的海滩保护和修复思路。

Abstract:
Coastal erosion is a common problem faced by all coastal countries. Beach nourishment is the best approach to protect sandy coasts, which is extensively used worldwide. This paper reviews the development of beach nourishment technology and the practices of beach nourishment worldwide, and summarizes the differences of beach nourishment concepts in various countries. The progress of beach nourishment technology in the aspects of sand filling modes relative to planform and cross-shore section, the synergetic engineering techniques of nourishment and the numerical models for predicting beach nourishment projects were summarized based on literature review. Furthermore, the future development trend of beach nourishment is proposed as 1. applications of beach nourishment to complex coasts, 2. beach nourishment and restoration based on coastal sediment management, 3. beach nourishment technology integrated with consideration from geomorphic system to ecosystem and 4. innovative beach restoration ideas under the context of global sand source deficit.
Key words:  marine geology  beach nourishment  restoration technology  development trend  sandy coast
