山东半岛近岸泥质区（又称“山东泥楔”）是山东半岛及其沿岸过去万年以来气候和环境演化的理想研究对象，承载着该区全新世以来海平面变化、古气候变化、海洋环流、生物地球化学循环等信息。然而由于缺乏一个详细高分辨率的年代模式，对该泥楔细粒沉积体系形成的动力学机制及其对区域气候环境变化的响应机理仍不清楚。为此，本项目拟对该区进行多时间尺度综合研究，采取现代观测与古海洋研究相结合，对关键区域建立海流等的长期定点观测，走航式观测获得关键剖面的地层分布；进行岩心取样古海洋研究和现生有孔虫研究，恢复该区全新世以来不同时间尺度上高分辨的古气候和古海洋环境记录。查明全新世以来山东半岛南岸和北岸古气候变化的差异性，阐明其对全球气候变化周期性和快速气候事件的响应。最后，通过开展数值模拟，明确“山东泥楔”形成的动力机制和沉积发展趋势，为山东省“透明海洋”和“海洋牧场”重大工程的实施可持续性提供可靠的科学依据。

The coastal muddy area of Shandong Peninsula (also known as "Shandong Mud Wedge") is an ideal research object of climate and environmental evolution in Shandong Peninsula and its coastal areas over the past 10,000 years. It bears the information of sea level change, paleoclimate change, ocean circulation and biogeochemical cycle since Holocene. However, due to the lack of a detailed and high-resolution dating model, the dynamic mechanism of the formation of the fine-grained sediment system and its response mechanism to regional climate and environmental changes are still unclear. For this reason, this project intends to carry out multi-time scale comprehensive research in this area, combining modern observation with paleo-oceanic research, establishing long-term fixed-point observations of ocean currents and other key areas, obtaining stratum distribution of key sections through navigational observation, conducting core sampling paleo-oceanic research and existing foraminifera research, and restoring high-resolution paleoclimate at different time scales in this area since Holocene. And paleo-marine environmental records. To find out the difference of paleoclimate change between the southern and northern coasts of Shandong Peninsula since Holocene, and to clarify its response to the cyclical and rapid climate events of global climate change. Finally, through numerical simulation, the dynamic mechanism and sedimentary development trend of the formation of "Shandong Mud Wedge" are clarified, which provides a reliable scientific basis for the sustainability of the implementation of the major projects of "Transparent Ocean" and "Marine Ranch" in Shandong Province.
