Abstract: Apriori algorithm, as a classical association rule data mining method, is applied to the forestry information management system. In this paper, a new method is brought forward for abtaining effective association rules from subcompartments,administrative areas, rivers, roads and so on. With a county-level city as an example, somepreliminary results have been achieved.
