The stoichiometric characteristics of coal mining subsidenee soil in Huaihai Economic Zone influenced by reclamation time, reclamation methods and other factors were analyzed using Meta analysis method. The pH,soil organic matter (SOM), total nitrogen (TN), available phosphorus (AP) and available potassium (AK) of the reclaimed soil in the coal mining subsidence area and the surrounding standard farmland soil were compared. The results showed that the contents of SOM and AP of reclaimed soil were significantly lower than those of standard farmland (P<0.05). compared with standard farmland the pH, TN and AK of reclaimed soil were not significantly diferent (P>0.05) . The pH and AK effect values of reclaimed soil was positive, and the TN effect values was negative. At the soil depth of 0~20 cm (cultivation layer), the contents of soil nutrient except SOM and AP were not significantly different from those of standard farmland (P>0.05). The soil nutrient contents could almost return to the standard farmland level after 10~13 years of reclamation. The effect of soil reclamation in coal mining subsidence area was affected by the reclamation methods and reclamation time, and varied in different soil levels and regions. In order to achieve the best recovery effect, it is necessary to adjust measures to local conditions, and adopt appropriate reclamation methods after comprehensive consideration.
