  • Grid method is employed for sampling covering soil at the test field, which is reclamation area filled by coal mining wastes for cropland in the Fushun coal mine, Liaoning Province, the Northeast China. The soil samples are taken at different locations, including three kinds of covering soil, three different depths of soil layers and four different covering ages of covering soil. The spatial-temporal variation of heavy metal element content in reclamation soil is studied. The results indicate that the content of heavy metal elements is decreasing year after year; the determinant reason why the content of heavy metal elements at 60cm depth layer is higher than that at 30cm depth layer and surface is fertilizer and manure apphcation; the metal elements mainly come from external environment; there is no metal pollution coming from mother material (coal mining wastes) in plough layer of covering soil.

SPATIAL-TEMPORAL VARIATION OF HEAVY METAL ELEMENTS CONTENT IN COVERING SOIL OF RECLAMATION AREA IN FUSHUN COAL MINE

Abstract: Grid method is employed for sampling covering soil at the test field, which is reclamation area filled by coal mining wastes for cropland in the Fushun coal mine, Liaoning Province, the Northeast China. The soil samples are taken at different locations, including three kinds of covering soil, three different depths of soil layers and four different covering ages of covering soil. The spatial-temporal variation of heavy metal element content in reclamation soil is studied. The results indicate that the content of heavy metal elements is decreasing year after year; the determinant reason why the content of heavy metal elements at 60cm depth layer is higher than that at 30cm depth layer and surface is fertilizer and manure apphcation; the metal elements mainly come from external environment; there is no metal pollution coming from mother material (coal mining wastes) in plough layer of covering soil.
