It is discussed in this paper the statistical analysis with the metrological method on the citations (excluding bulletins and experimental reports) in the papers published in 1990 by the Acta of 7 major agricultural universities and colleges who are under the direct jurisdiction of the Ministry of Agricu- lture. In the analysis, 577 papers are covered with 4290 pieces of citations. The statistical data includes the numbers, languages and types of the citations, years of the citations published, percentage of self citation, distribution of the cited periodicals,and the most important Chinese and foreign periodicals cited with high frequency. The results have revealed that each paper carries 8.23 pieces of citations on average with 48.5% in Chinese language and 51.5% in foreign languages. In terms of types of the cita citations, periodicals acco- unt for 73.6% while books and specific documents for 26.4%. As for years of the citations published, 3 years seems to be most optimal for Chinese literatures and 7 years for foreign ones. The half life of the Chinese litera- tures is averaged at 4.97 years while that of the foreign ones at 10.6 years. The authors′self citation is rated at 11.1% while the journals′self citation at 4.0%. Out of the 7 universities and colleges, 6 has been found that their own journals are the very periodicals tobe be cited with the highest frequency.
