The invention provides a rule extraction method, which specifically comprises the following steps of: extracting a rule of each non-root node in a tree integration model, selecting rules meeting a granularity level in different decision-making trees to combine, and continuously combining rules meeting the granularity level in the combined new rules with rules meeting the granularity level in another decision-making tree to obtain a combined rule; all the rules are combined and merged; and counting new rules covering most positive examples in the combined rule set and randomly selecting one of the new rules until all positive examples are covered. The method is a universal technical framework, and parallel computing is introduced into the field for the first time, so that the expansibility and efficiency of the model are improved; the complexity of a tree integration model is remarkably reduced, an interpretable rule list with non-redundant information is generated, and excellent classification performance is
