海洋沉积动力学研究与应用前景展望

Applied Marine Sediment Dynamics:A Prospect

海洋沉积动力学正在打破传统，走向海洋工程学、物理海洋学和地质学的联合，共同建立一门综合性的、统一的沉积动力学。其技术手段包括：悬沙输运的动力学模型方法、以力学为基础的半经验公式、经验公式、人工和天然示踪沉积物技术、地貌学信息方法、沉积学信息方法、以及现场直接观测。国际国内的研究动态均表明，这些方法的建立和完善将为海洋沉积动力学在海底地貌演化、生态系统的维护和改造、人类活动对环境影响的评估、海洋资源开发和特续发展战略制定等方面的应用提供广阔的前景。

Significant progress in the establishment of a unified marine sediment dynamics has been made through the joint effort by physical oceanographers,coastal engineers and marine geologists. The methods and techniques used in this research area include matheinatical models for suspended sediments, mechanics-based semi - empirical formulae, empirical formulae, artificial tracer techiques, the natural trace sediment method,geomorphological information, sedimentological information, and direct measurements, These methods have many practical applications such as marine geomorphology, the protection of fragile coastal ecosystems,environmental impact assessment and coastal management.
