渤海沿岸风暴沉积体的研究

A Study of Storm Sedimentary Bodies Along the Coast of Bohai Sea

渤海沿岸是风暴潮常发地区之一。温带气旋和热带风暴作用形成该区的风暴沉积体。研究风暴沉积体的特征及其分布规律 ,探讨全新世以来风暴作用对沿岸地质环境演化影响及沉积模式。进行野外地质调查和历史资料研究 ,综合研究渤海沿岸风暴潮动力环境。渤海沿岸的风暴沉积体表现为滨岸沙堤、贝壳堤、风暴沉积砂层等地质体。保护风暴沉积体 ,合理开发利用 ,提出减轻灾害的措施和对策 ,有利于当地经济的可持续发展。

Storm surges occurred frequently along the coast of Bohai Sea, and the storm sedimentary bodies were formed by the actions of temperate cyclones and tropical stroms In this paper, the features and distribution regularities of storm sedimentary bodies are studied, and the influence of the storm actions on the coastal geologic environment evolution and the storm sedimentary model are explored The field geologic investigations and the historical data study were made to study the storm surge dynamic environment along the coast of Bohai Sea The storm sedimentary bodies feature various geologic bodies such as offshore sand bar, shell bank and storm sedimentary sand layer The protection, rational exploitation and utilization of the storm sedimentary bodies and the measures to mitigate the disaster will be helpful to the sustainable development of local economy
