摘　　要：伊犁谷地野核桃林下的土壤有均腐殖质性，Ｒｈ０．３１～０．３９，腐殖质组成以胡敏酸为主，Ｅ４值较高，弱粘化，钙积现象，Ｂａ值较高，粘土矿物以伊利石、蛭石、蒙脱石为主，淋溶较弱，风化程度不高．四个研究剖面分类为均腐土纲，干润均腐土亚纲，粘化干润均腐土类、钙积干润均腐土类，简育干润均腐土类．根据暗沃表层的厚度，划分相关的亚类．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.
