海洋开采技术的发展及对海洋生态系统的影响

In this paper,the variations in submarine topography and coastal dynamics caused by sand exploitation are studied by studying the modern action processes of coastal beach,submarine topography and coastal geomorphology and making numerical simulation,and the dynamic impacts of the variations on sea bottom and coast are analyzed.

分析了岸滩、海底地形和海岸地貌现代作用过程,用数值模拟方法研究了海沙开采导致的海底地形改变,以及由此引起流场及波浪折射而造成的海岸动力变化,讨论了这种变化对海底和海岸的动态影响。
