| Abstract: | The soil under the wild-walnut forest possesses the Isohumic property.The Rn value is 0.33-0.39.The humus mainly consists of HA.The E 4 value is much high.The soil has a para-argic-calcic evidence.The Ba Value is much high.The clay mineral chiefly includes illite,vermiculite and montmorillonite.The leach is week.The soil in weathing is low.The classification of five studied-profiles is Isohumisols,Vstic Ishumisols,Arg-Ustic Isohumisols,Cal-Ustic Isohumisols and Hap-Ustic isohumisols.According to the mollic epipedon thichness,the soil is classified into relevents subgroups. |
