中文摘要：

文章试图在海岸与陆架沉积的基本动力过程、全球变化影响和地层记录等方面提出新的科学问题和基础研究建议。在基本动力过程研究上，底部边界层过程的垂向尺度和悬沙浓度影响、陆架环流和水团运动的悬沙输运效应、河口与陆架密度流形成机理、大型河流的水下三角洲和斜坡沉积的形成过程、浊流运动特征以及物理海洋过程响应等是值得重视的问题；在全球变化影响方面，需深入研究流域变化和生物礁演化与碳埋藏的关系、沉积环境的系统状况转换及动力过程变异、沉积体系演化的定量模拟方法等问题；在地层记录方面，应加强陆架与海岸沉积体系中全球变化记录的高分辨率信息提取、多种沉积记录信息的整合方法、沉积体系和记录形成的数值模拟、气候变化效应的地层记录模拟、沉积体系的信息分析模型等研究。

英文摘要：

The present paper attempts to propose some research topics for the field of Quaternary studies, on the basis of an examination of the scientific problems associated with coastal and shelf sediment dynamics in relation to the global change impacts and the resultant geological records. In terms of the basic dynamics processes, important issues include the vertical spatial scale and the suspended sediment concentration of the water column that influence the benthic boundary layer, long-distance suspended sediment transport caused by shelf circulation and water mass movement, the mechanisms for the formation of hyperpycnal flows in estuaries and on the continental shelf, processes associated with the subaqueous delta and alongshore clinothems, and physical oceanographic responses to turbidity current events. For the ＂global change impacts＂ ,there is a need to study the carbon burial patterns in response to catchment changes and biological reef evolution, the system status transfer that influences the dynamic process patterns, and the approaches to quantitative modeling of the formation of sediment systems. For a sound understanding of the sedimentary records, it is important to undertake high resolution analysis of the coastal and shelf sequences within the framework of Holocene global changes, to establish new methods for analyzing multisourced sedimentary records and for modeling the formation of the sedimentary system and records （including the records of the effects of climate changes） ,and to develop an information analysis tool for the Holocene coastal and shelf sedimentary records.
