：美国物理学家乔治·赫希提出的h指数是用来评价科学研究人员研究成果的一种新思维和方式，自提出以来便受到了图情界乃至学界的关注及应用，在个人学术评价、学术期刊评价等领域形成了丰富的研究文献。文章通过对h指数应用于图书馆实践的研究文本进行分析可以发现，h指数对图书馆实践应用与学术研究都有着很大的发展空间。基于h指数的图书馆资源采购与情报服务是未来h指数应用于图书馆服务的两大延伸方向，但在具体应用过程中需要注意多种评价指标的综合应用、动态监测等事项。

The H Index proposed by American physicist George Hirsch is a new thought and method used to evaluate the research results of scientific researchers, which has been paid attention to and applied in the field of knowledge and academia since its inception. This theory has formed rich research literature in the fields of individual academic evaluation and academic periodical evaluation. Through the analysis of the application of H index to library practice, it can be found that there is great development space for the application and academic research of library based on H index. The Library resource purchasing and information service based on H index is the two extension directions of the future H Index application in library service, but it is necessary to pay attention to the comprehensive application and dynamic monitoring of various evaluation indexes in the application process.
