Abstract:
The distribution characteristics of heavy metals at different depth in the vertical soil section under two different land use patterns, that is, artificial apple wood land and agricultural land, were analyzed in Changwu county of Shaanxi province. The results indicated that the heavy metal contents in the topsoil of artificial apple woodland are higher than that of agricultural land, the contents of heavy metals are high in 20～40 cm, the fluctuation of agricultural soil section is more obvious than that of artificial soil section, especially in 0～60 cm. The effect intensity of land use pattern on heavy metal contents in different soil depths is different, with the greatest effect in the soil layer of 20～60 cm.
