利用可公度理论中的三元-五元可公度式及其拓展式,从粗粒度角度对郑州地区从1901年-2000年严重干旱等级以上记载年份进行可公度数统计和分析,依据预测结果结合数据挖掘理论中的关联规则算法作进一步推演和修正,结果表明该方法预测准确率达80%,同时预测从2013年-2015年郑州市不会发生严重以上等级干旱.
利用可公度理論中的三元-五元可公度式及其拓展式,從粗粒度角度對鄭州地區從1901年-2000年嚴重榦旱等級以上記載年份進行可公度數統計和分析,依據預測結果結閤數據挖掘理論中的關聯規則算法作進一步推縯和脩正,結果錶明該方法預測準確率達80%,同時預測從2013年-2015年鄭州市不會髮生嚴重以上等級榦旱.

@@@@he three‐element and five‐element formula of commensurability theory and their expansion formula were used to calcu‐late and analyze the commensurability of the record years with severe drought in Zhengzhou from 1901 to 2000 from the aspect of coarse granularity .The association rule algorithm of the data mining theory was used to verify the predicted results ,which in‐dicated that this method has prediction accuracy as high as 80% .Moreover ,it was predicted that there would be no more severe drought in Zhengzhou between 2013 and 2015 .
