| 摘 要： | 沉积地球化学是沉积学的重要研究内容和手段，在认识地球表层系统圈层相互作用和资源环境效应方面发挥着不可替代作用。随着国家科研经费投入的增加，以及地球化学分析测试的平台建设和技术进步，中国沉积地球化学进入快速发展期，在国际上的学术影响力逐渐增强，但是在技术方法与理论的创新、及高质量成果产出等方面，仍有待改进。因此，中国沉积地球化学应加强统筹规划和布局，在战术上重视理论、方法和技术的发展与创新，提升沉积-成岩过程年代的约束能力，重视对地球化学数据的精细提取和模型定量分析；在战略上加强沉积地球化学在大时空尺度的应用与探索，深化对关键地质时期地球环境-生物协同演化，以及沉积矿产和化石能源的形成与演化等重大科学问题的研究。在此基础上，中国沉积地球化学将进一步提升研究水平和国际地位，并有望实现跨越式发展。

| Abstract: | Sedimentary geochemistry is an important content and tool of sedimentary study, playing an essential role in understanding the evolution of Earth surface system and related resource-environment effects. With the increasing investments in scientific and technological researches, and the laboratory platform construction and technological advance in geochemical analysis, the studies of sedimentary geochemistry in China have stepped into a period of rapid development and gained increasing academic influences in the world. However, to narrow the gap with international leading countries and/or academic communities, sedimentary geochemistry studies in China should persistently aim to more high-quality outcomes and innovations, particularly in aspects of analytical technologies, methods and basic theories. Therefore, the Chinese sedimentological community should strengthen the overall planning and strategic arrangement for the development of sedimentary geochemistry:1) in term of tactics, strive for development and innovation in geochemical theory, method and technology; enhance high-resolution geochronological constraints on sedimentary and diagenetic process; promote the ability of accurate extraction and quantitative modeling for geochemical data; 2) in term of strategy, explore the evolution and distribution of geochemical proxies in greater geological space and time scale; intensify the applications of sedimentary geochemistry on critical scientific issues, such as the co-evolution of geological environment and life at critical transitions in Earth's history, and the formation and evolution of sedimentary ore deposits and fossil fuels. In this context, sedimentary geochemical studies in China are expected to further improve the academic achievement and influence in the world, realizing leapfrog development. |
