Spatial-temporal variance of reclamation soil physical and chemical character in opencast mine region

         

摘要

In order to study the effects of soil compaction, and soil physical and chemical characteristics after land reclamation, selected lands that were reclaimed after 1, 2, 3, 4,and 5 a, respectively, in the Majiata Mine of the Shendong Open Pit; tested the effects of soil compaction; and collected soil samples from 5 different depths, which are 0~7.62,7.62~15.24, 15.24~22.86, 22.86~30.48, and 30.48~38.10 cm, respectively. The results show that: ① Land reclamation leads to soil compaction. The lowest effect of soil compaction is in the top layer and the highest one at the depth of 20-30 cm; ② The bulk density of reclaimed soil is higher than that of undisturbed soil; this declines with the reclamation and nearly reaches the level of undisturbed soil after 5-year reclamation; ③The content of reclaimed soil nutrients is lower than that of undisturbed soil. The lowest one is in the soil dumping site, which reaches the level of undisturbed soil after 5-year reclamation; ④ The pH value of reclaimed soil is lower than that of undisturbed soil. The highest one is in the soil dumping site; this declines with the reclamation.
