Based on the field observation and indoor determination,an investigation in Loess Hilly Region was made on vertical distribution of fine root characteristics and soil properties with in the recovery of artificial Pinus tabulae formis.The results showed that:(1)The ability to improve soil structure under the low-density pine forest was better than that under mid-density and high-density forest,and the logging area was the worst.(2)In the 0.300cm layer,the soil moisture content declined with the increasing density,and was 12.95%,12.87%,12.78% and 17.10% respect ively for low-density pine,mid-density,high density pine and logging area,indicating that the soil moisture content of logging area was recovered to some extent.(3)Pinus tabulaeformis roots were mainly distributed in 0-60cm soil layer.(4)There were close relationship between root distribution and soil characteristics,especially in the 40-60 cm layer,where the relationship were very significant.
