摘要: 国家自然科学基金委员会深入推进新时代科学基金改革的背景下,地球科学部大气科学学科率先开展申请代码设置改革,新版申请代码设置方案于2020年投入使用并在实施过程中不断优化。本文主要针对大气学科二级代码D0506大气化学下设研究方向和关键词设置的主要依据进行解读;同时基于文献计量学方法对该代码下不同研究方向的词频、研究热点和趋势进行分析和讨论。新版代码设置方案统筹考虑主要研究方向和研究手段,并根据关键词属性进行分类,便于基金项目申请和评审。基于关键词的文献计量分析明晰了分支学科当前存在的问题及资助导向,有助于进一步促进大气化学及相关方向的发展。Abstract: The Department of Atmospheric Sciences of the National Natural Science Foundation of China (NSFC) took the lead in reforming the application code setting scheme and putting the new version into use in 2020, and since then, it has been continuously improved. The new version of the code setting scheme considers the main research directions and methods and sorts out the main keywords to facilitate the application and evaluation of NSFC projects. This paper summarizes the primary considerations for establishing the research directions and keywords in the subcode D0506 atmospheric chemistry. Simultaneously, the word frequency, research hotspots, and trends in different directions under the subcode are analyzed and discussed. The keyword-based bibliometric analysis highlights existing difficulties and funding priorities with the intention of promoting the development of atmospheric chemistry and relevant areas in the atmospheric discipline.
