| Abstract: |
| Its necessary to research the prioritization sequence of different filled reclamation modes based on the soil
fertility and environmental quality in the subsiding mining area. We could find the existential problems of different filled
reclamation soil both in short -term and long-term to ensure selecting and changing the management task pertinently
according to the research result. Taking Jiawang, Xuzhou as an example, the paper finished the soil quality evaluation and
sequencing of the filled reclamation modes with the methods of soil column experiments, the field investigation and the
scientific calculation. The results showed that the filled reclamation modes in the sight of soil fertility were sorted as silt>
fly ash> gangue> construction rubbish (short-term) and fly ash> gangue> silt> construction rubbish (long-term), and that in
the sight of soil environmental quality were sorted as silt> construction rubbish= gangue> fly ash (short-term) and silt>
construction rubbish> gangue> fly ash (long-term). |
