Assessing Soil Zn Content Using Decision Tree Analysis
基于决策树的土壤Zn含量预测

Taking Fuyang county of Zhejiang Province as the study area,the present study estimated soil Zn concentration(divided by its local background value into G1,G2,G3,G4 and G5) using CART methods,based on 184 soil samples(0-20 cm).The environmental factors used to infer the Zn concentration rules included soil types,pH,organic matter,agricultural land uses,industry plant types,road and village density.The other 41 soil samples were used to test the prediction results.The Zn concentration classes estimated by CA...
