- Abstract:
-
Three types of subsidence from coal mine subsidence in Huainan City were sellected for evaluation, including unstable subsidence area, stable subsidence area and restoration area. The soil physical chemical properties and soil enzyme of the soil layers were analyzed. The results showed that the soil physical properties, the soil nutrient and the soil enzyme decreased during the process of the change of unstable subsidence area into stable subsidence area. It was found that the unstable subsidence area had the highest integrated fertility index (IFI) and soil enzyme index values (ISE) and the integrated fertility index and soil enzymes index values of the restoration area was higher than the stable subsidence area. The soil biological fertility decreased with the increase of soil depth. Urease and invertase were highly obviously correlated with soil physical and chemical properties, suggesting that urease and invertase could be used as feasible indicators to assess change of soil nutrients in coal mining subsidence area.
