对2023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分析，包括项目申请、受理、同行通讯评议、会议评审以及资助情况等，并通过对学科近5年项目申请情况的分析，提出学科发展面临的挑战。结果显示：\mathrm{①}2023年度地球化学学科项目申请量相比2022年度减少5.1%，但申请项目的依托单位数量近几年保持连续增长；\mathrm{②}表层地球化学作为学科新增代码，项目申请量增长较快，2023年度已进入学科前3位，成为学科领域的新增长点；\mathrm{③}近5年地球化学学科项目申请人、负责人的年龄均较地球科学部平均年轻1岁以上。总体而言，地球化学学科目前面临体量基数小和增长慢的挑战，也存在研究队伍相对年轻化的优势。学科未来既需持续加强自身理论和方法的基础研究，又要着力强化支持地球化学的应用研究。最后对2022年度结题项目的代表性成果进行了介绍。

We analyzed the 2023 funding schemes managed by the Division of Geochemistry (application code: D03), Department of Earth Sciences, National Natural Science Foundation of China, with the goal of understanding the challenges faced by the foundation and finding solutions. Data from the past five years related to the number and type of applications, rate of acceptance, peer review process, and funding status were included in our analysis. The summarized results show that: \mathrm{①} the total number of applications received by the Division of Geochemistry has decreased by 5.1% compared with the number received in 2022; \mathrm{②} in terms of research field, the group of applications coded as “surface geochemistry” was the fastest growing group, entering the top three codes in the Division of Geochemistry; and \mathrm{③} the applicants and principals of projects in the Division of Geochemistry are all more than one year younger than the average age of all applicants under the Department of Earth Sciences. Overall, the Division of Geochemistry faces the challenges of small quantity of projects and slow growth; however, it has the advantage of relatively young research teams. To strengthen future development in the field of applied geochemical research, continued support of basic research (including theoretical and methodological studies) is needed on theories and methods. The research advances presented in project reports completed in 2023 are also discussed.
