北大岭铁矿尾矿库绿化研究

Study on the Greening of Beidaling Iron Mine's Tailings Dam

通过对北大岭铁矿尾矿库不同部位土壤成分和种植植物的研究发现,北大岭铁矿尾矿沙严重缺乏植物生长所需的大量元素和有机质。铁矿尾矿库不同部位种植的植物生长差异很大,主要由尾矿库不同部位土壤元素含量有很大差异造成的。在铁矿尾矿库内不覆土的情况下,不同部位选择适宜树种和科学的种植方法,既节约人力物力,也会达到很好的绿化效果。

Through studying on the soil constituents and planting in different areas of Beidaling iron mine＇ s tailings dam, it was found that this area was seriously lacking of nutritive elements and organic matters which were necessary to plants growth. The plant growth varied significantly in different parts of Beidaling iron mine＇ s railings dam, due to the different parts of the elements in the soil. If the iron mine＇ s tailings dam without earth cover, it was necessary to choose suitable species and scientific planting methods, which could not only save human and material resources, but also achieve a good greening result.
