Abstract: The relationship between soil depth and soil enzyme activity,and the effect of soil enzyme activity under different land use are under research by choosing the 0~20 cm,20~40 cm and 40~60 cm soil layer of differentland use which are woodland,dry land,orchards and shrubs,in Xinzhai,Dajing ofGuilin.And the determination of enzyme activity of urease,invertase and peroxidase are tested by using colorimetric method.The results showed that the enzyme activity of soil urease and invertasereduced gradually with increased soil depth in same land use patterns.The peroxidase activity increased with increased soil depth.While under different land usepatterns,the soil urease,invertase and peroxidase activity showed significant differences in size.

Key words: utilization mode, soil enzyme, urease, invertase, peroxidase
