Abstract:
      Through determination of soil moisture under artificial forest in the southern suburb of Xi'an in normal year and wet year, change and restoration of soil moisture underground from 0～6 m are studied.The results show that soil moisture content underground between 2～4 m under artificial forest is from 9% to 10% in Xi'an region in normal year and soil moisture is low.However, in wet year soil moisture underground between 2～4 m is from 18% to 24%, and is 8% higher than that of normal year.The soil moisture content underground from 4～6 m goes up obviously in wet year.From analysis it is also found that, in wet year, the soil moisture can not only be restored but also the restoration depth can reach 5 m and the speed is also very quick.
