决策树在耕地地力等级评价中的应用

摘要

在介绍数据挖掘技术的基本概念、决策树方法的基础上,结合牡丹江市地力等级数据样本,采用决策树 ID3 分类算法建立了耕地地力等级决策树分级图.通过该分级图可以预测各地区耕地地力等级,为该领域的数据挖掘提供了合理的挖掘方式.%Based on introducing the concept of data mining technology and the decision tree method, combining Mudanjiang soil grade data sample, using decision tree ID3 classification algorithm, cultivated land fertility level decision-making tree grading figure was established.Through the classification figure could predict various areas cultivated land fertility level, provide the reasonable mining mode, and the effective analysis conclusion was gotten.
