摘要： [目的/意义]针对h指数难以反映学者动态学术影响力问题，为描绘学者不同时段学术影响力动态变化提出附加时间限制的改进指标——历时h指数（TDh指数）。[方法/过程]采集国内图情领域期刊的CSSCI被引数据，采用批量统计法计算全部学者多个时段的TDh指数，以实例论证TDh指数的合理性及应用价值。[结果/结论]TDh指数可描绘学者在学术生涯不同时段的影响力波动情况，研究者可根据不同学术群体的影响力升降情况发现领域新秀及热门研究，并从宏观上观察领域研究主题的兴衰及热点变迁。

Abstract: [Purpose/significance]To solve the drawback that h-index can not reflect Scholars' dynamic academic influence, this paper puts forward TDh-index by attaching time limit to original h-index.[Method/process]This paper collects citation data of journals of library & information science from CSSCI, and uses the large-scale extracting approach to get all the scholars' TDh-index in multiple periods. Finally, the paper uses empirical analysis to demonstrate the rationality and application value of TDh-index.[Result/conclusion]TDh-index can reflect the academic influence in different periods of scholars' career. Researchers can find stars and research hotspot according to academic influence change of different academic groups, observing research subject and research hotspot change at the macroscopic scale.

Key words: h-index, TDh-index, library & information science, academic influence, research hotspot
