摘要：Land subsidence caused by underground coal mining is one of the most prominent environment problems in China.The reclamation of mining subsidence land with Yellow River sediment was considered to be feasible,but its effectiveness needs to be verified.An integrated reclamation technology with Yellow River sediment was evaluated using a comparison of actual crop production soil profile analysis in Jining City,China.The results indicated that reconstructed soil profile of the reclaimed farmland was less effective in retaining water and in supporting plant growth than that of the unaltered farmland.Some measures are proposed,such as reducing the drainage velocity to allow sedimentation and retention of the clay and silt,changing the techniques of filling the Yellow River sediment and increasing the organic matter content in the soil layers to improve the capacity to retain water in the reclaimed farmland.
