对国家自然科学基金委员会地球科学部地球化学学科（申请代码D03）2025年度各类基金项目的申报情况和2024年底结题项目的情况进行了系统分析。相较于2024年度，2025年度地区基金的申请数量有所增加，面上项目和青年科学基金项目（C类）略有减少；青年科学基金项目（C类）连续2年的申请量明显低于面上项目。近5年来，申请项目依托单位的总数量连续增长，表层地球化学（D0310）继续成为学科新的增长点。2025年度地球化学学科4项项目因未按要求提供相关材料而未予受理。2025年度地球化学学科面上项目、青年科学基金项目（C类）和地区科学基金项目的送审率分别为154.7%、154.7%和141.7%，资助率分别为17.9%、18.4%和11.1%，平均资助金额分别为53.1万元/项、30.0万元/项和30.9万元/项。2024年度面上项目、青年科学基金项目（C类）和地区科学基金的结题项目及2021年度立项的青年科学基金项目（B类）结题成果及第一标注成果有待加强。近年来，地球化学学科申请体量小、增长慢的特点仍未改观。未来应在保证地球化学学科优势方向的基础上，加强基础研究与目标导向和国家需求的深入结合，促进学科内交叉、跨学科交叉和跨学部交叉研究，拓展地球化学学科研究的深度与广度。

Abstract: This paper systematically analyzes the application, acceptance, evaluation, and funding of the projects managed by the Geochemistry Discipline (Application Code: D03) in the Earth Science Department, National Natural Science Foundation of China in 2025, and analyzes the project completion and precautions in 2024. The number of applications for the General Program, Young Scientists Fund (Type C), and Fund for the Less Developed Regions in the Geochemistry discipline showed a fluctuating upward trend respectively during the 2020-2025. For two consecutive years, the number of applications for the Young Scientists Fund (Type C) has been significantly lower than that of the General Program. In the past five years, the total number of support organizations applying for projects has kept increasing continuously, and Earth’s surface geochemistry (D0310) has become a new growth point of the discipline. The General Program and Young Scientists Fund (Type C) are mainly based on “Free-exploration basic research”, while the Key Programs in the field of “Resource and energy formation theory and supply potential” are mainly based on “Goal-oriented basic research”. In 2025, four projects in the geochemistry discipline were not accepted due to reasons such as failure to provide supporting materials, recommendation letters, supervisors' consent letters, ethics committee certificates as required, and missing items in the application forms. In 2025, the review submission rates of the General Program, Young Scientists Fund (Type C), and Less Developed Regions of Geochemistry discipline were 154.7%, 154.7%, and 141.7%, respectively. The funding rates were 17.9%, 18.4%, and 11.1%, respectively. The average funding amounts were 531,000 yuan per project, 300,000 yuan per project, and 309,000 yuan per project, respectively. The funding achievements and first-labeled achievements of the General Program, Young Scientists Fund Program (Type B and Type C), and Fund for the Less Developed Regions completed at the end of 2024 need to be improved. Hereby, it is recommended that the Principal Investigator of uncompleted geochemistry projects must further understand and follow the management guidelines of the National Natural Science Foundation of China, and ensure the standardization of achievements labeling, especially for the high-level achievements. In recent years, the geochemistry discipline has remained characterized by a relatively small number of applications and slow growth. In the future, on the basis of maintaining the advantageous directions of the geochemistry discipline, efforts should be made to strengthen the in-depth integration of basic research with goal orientation and national needs, and to promote interdisciplinary research, cross-disciplinary research, and transdisciplinary research to expand the depth and breadth of geochemistry research.
