从国家自然科学基金项目资助探讨大地测量学的学科架构与发展

Exploring the Geodesy principle architecture and development from the perspective of Granted NSFC Projects

大地测量学是地球科学的一个重要发展领域,通过对地球和行星几何与物理量的观测与分析,研究地球和行星几何形状、物质运动状态及其空间环境响应,为国家基础设施和国防建设提供时空和重力基准保障。随着大地测量学向地球科学基础研究和交叉应用等方面的不断延伸和快速发展,其研究水平得到了显著提高,在描绘、构建和认知地球和行星中占据了越来越重要的地位。本文基于历年来国家自然科学基金申请和资助项目,从项目类型、分支领域、依托单位、研究方向和关键词等方面进行了统计分析,梳理了学科发展特点,构建了学科架构知识图谱——大地测量学科树,以期为大地测量学领域相关学者提供参考。

As a significant development field of Earth science,Geodesy is concerned with the meticulous observation and analysis of the geometric and physical characteristics of both the Earth and planets,which inform our understanding of their shape,material movement status,and space environmental response.Moreover,this discipline plays a pivotal role in the provision of spatio-temporal and gravity benchmarks,which are instrumental in the construction and maintenance of national infrastructure and defense.With the continuous extension and rapid development of Geodesy moving forward to both sides of earth science fundamental research and cross-application of relevant technologies,its research capability has been significantly improved,especially playing an increasingly important role in depicting,structuring and recognizing the Earth,in solving issues of earth science.Based on the application and funding projects of National Natural Science Foundation of China(NSFC)over recent years,this paper performs a statistical analysis in terms of the project types,branch fields,supporting units,research directions,and key words,discusses the development characteristics of the discipline,and constructs knowledge map of Geodesy discipline architecture—Geodesy discipline tree,aiming at providing valuable reference for scholars of Geodesy-related field.
