【摘要】 关键词标引是文献检索中最基础也最重要的环节。地质学论文具有很强的学科特色，本文从读者检索的角度出发，针对地质学研究的时空特点，归纳总结了地质学论文在研究区域和地质时代的关键词标引中存在的问题。地质学是研究地球及其演变的一门自然科学，其研究对象的空间尺度变化大，时间跨度长，因此，表达地质学时空概念的词汇通常是地质学论文关键词检索中优先选择的检索词。一篇优秀的论文应准确选择关键词标引。在地质学论文的区域范围关键词标引中应避免表示的研究区范围过大或过小以及选取的关键词随意性太强，将一些泛义词选作关键词等问题;在地质年代和年代地层的关键词标引中应避免出现二者的混淆使用及使用废弃的地质术语和地质年代范围词组等问题。更多还原

【Abstract】 Keywords selection is a basic and important step in literature retrieval. Geological papers possesses strong disciplinary characteristics. This article started from the perspective of retrieval by the authors and summarized the issues in keywords selection of geological research papers in regional geology and geochronology.Geology is one of the subjects of natural science focusing on the study of the earth and its evolution,which characterized by great spatial variation and extremely long time span. Therefore, the keywords selected shall reflect geological temporal and spatial concepts. Accurate keywords to be indexed can improve the success rate of literature retrieving. When editing geological keywords reflecting the study area, several issues may consider. The keywords chosen might be unspecifi or arbitrary,and wrong in terms of geochronology and stratigraphy, or out-of-date. The standardized use of geochronological terms can accurately express the connotation of a geological concept and thus facilitate the dissemination of the scientific ideas that the authors want to convey.The appropriateness of keyword selection can increase the possibility of the paper to be retrieved after publishcation and the utilization of the research results.更多还原
