对2022年度国家自然科学基金委员会地球科学部地球科学二处地球化学学科（申请代码：D03）所管理的基金项目进行总结，包括申请和受理、同行通讯评议和会评送审以及资助情况等，并对2021年度结题项目的研究成果进行介绍。\mathrm{①}2022年度地球化学学科基金项目的申请量保持稳定；\mathrm{②}申请项目的格式规范性有所提高，初审合格率明显高于往年；\mathrm{③}面上项目、青年科学基金项目和地区科学基金项目的平均送审率为143.5%；\mathrm{④}通过3年的“负责任、讲信誉、计贡献”评审机制试点，地球化学学科对约2 000名评审专家的评审态度与公正性及其对评审工作的贡献进行记录，探索如何更好地发挥同行评议对科学基金资助决策的核心作用；\mathrm{⑤}2021年度结题的项目在同位素地球化学、元素地球化学、地质年代学、宇宙化学和行星化学等方面取得重要进展。

We summarized the application, peer review, and acceptance of projects managed by the Division of Geochemistry (D03), Department of Earth Sciences, National Natural Science Foundation of China in 2022 and introduced the research advances of projects completed in 2021. The results were as follows: \mathrm{①} The number of project applications for the discipline of geochemistry remained constant in 2022; \mathrm{②} The application formats have improved, while the rates of applications passing preliminary examination were significantly higher than ever before; \mathrm{③} The submission rates in the General Program, Young Scientists Fund, and Less Developed Regions Fund exceeded 143.5%; \mathrm{④} By piloting the mechanism of "Responsibility, Credibility, Contribution" for three years, the Division of Geochemistry has recorded the attitudes, fairness, and contributions of approximately 2000 peer-review experts, in order to explore ways to better play the central role of peer-review in funding decisions; \mathrm{⑤} A significant progress has been made in Isotopic Geochemistry, Elemental Geochemistry, Geochronology, and Cosmochemistry in 2021.
