Abstract: Abstract: This paper analyzed the existing results on the star structure model of journal cross-citation for 2010 Chinese agricultural engineering journals. The results showed that the Transactions of the Chinese Society of Agricultural Engineering was at the core of all the agriculture engineering-related journals, and of remarkable impact in the agricultural engineering field. There was a large number of agriculture soil and water engineering-related journals in the key journals list of agriculture engineering, but the numbers of the journals on agricultural information and electrical technologies were small in the list of both the agriculture engineering-related journals and the key journals of agriculture engineering. It suggested that the numbers of journals on the agricultural information and electrical technologies are still scarce.
