摘　　要：论文通过对胜利露天煤矿南排土场土壤养分的调查分析,土壤质地的确定及土壤肥力的综合评价,得到该矿南排土场土壤质地为重壤土,土壤肥力贫瘠的结论。土壤肥力贫瘠是导致该矿区排土场、工业广场等地幼苗生长不良、苗木成活率不高的主要原因。今后应加强对排土场耐性豆科植物的种植以提高土壤肥力。After the investigation and analysis on the soil nutrient of the south dumping site in Shengli Surface Mine, the paper had a confirmation on the soil property and a comprehensive assessment on the soil fertility. The results showed the conclusion that the soil property of the south dumping site in Shengli Surface Mine was heavy soil and the soil fertility was poor. The soil fertility in poor was the main cause to the poor growth of the seedling and the low survival rate of the baby trees in the dumping site, industrial park and other places of the mining area. In the future, it shall be necessary to enhance the cultivation of the patience leguminous plants in the dumping site in order to improve the soil fertility.
