摘　　要：以《中国科学引文数据库》为数据源，对1998-2007年间的农业工程类核心期刊的h指数和相对h指数进行了统计分析。结果证实：各期刊1998-2005的年度h指数变化比较均匀，这跟这些期刊的被引半衰期基本一致；对于同领域类的期刊。年栽文量多的期刊会更有机会获得较高h指数；科技期刊的h指数越高，其学术影响力就越大。Taking Chinese Citation Database as the statistical sources, the paper analyses statistically the h-index and relative h-index of the core journals in agricultural engineering fields, The result of getting proved that h-index of annual ehanges in the journal more evenly, which are basically consistent with the cited half-life; Journals for the same domain class, more yearly quantity of papers of the journal will have the opportunity to obtain higher h-index; compared with the international jour- nals of agricultural engineering of JCR, reflecting the core journals of China＇s agricultural engineering academic influence are relatively large; The higher h-index of scientific and technical journals, the greater the influence of its academic.
