摘　　要：期刊影响因子是SCI学术评价的重要指标,而期刊论文的引文密度对影响因子值的计算有着很大影响。本文阐述了引文密度与影响因子的关系,针对现有SCI定量评价指标存在的缺陷,对引文密度指标进行了修正,并以地球科学重要期刊为对象,设计了引文密度修正指标的实验研究。研究结果表明引文密度修正指标具有一定的合理性。Journal Impact Factor（JIF） is an important indicator for SCI to make academic evaluation,while the citation density of a journal paper has a great effect on the calculation of the value of JIF.This paper discusses the relationship between citation density and impact factor.In view of the defects existing in SCI quantitative evalua-tion indicators at present,this paper revises the citation density indicators,and taking some important journals of earth science as the object,devises an experimental study of the revised indicators of citation density.The research results show the revised indicators of citation density has certain rationalities.
