摘要
通过对冀东地区铁尾矿库不同树种造林的植被恢复效果的调查,结果表明紫穗槐、刺槐是铁尾矿库造林的适宜树种,在人工覆土和密植的情况下短期内可取得良好的植被恢复效果;沙棘是裸尾矿砂直接造林的优良树种;人工植被尤其是豆科植物对土壤有机质和氮元素含量的改善能力较强,但对土壤磷元素含量的改善能力较弱。
In this paper artificial vegetation restoration of iron mine tailings reservoir were investigated in east of Hebei area.The results showed that Amorpha fruticosa and Robinia pseudoacia were suitable afforestation species on iron mine tailing re-servoir.In the conditions of close planting and covering soil,the artificial vegetation was grew well in a short time.Hippophae rhamnoides was suitable species in exposed mine tailing.The legumes plants had better effects in improving contents of soil organic matter and nitrogen than phosphorus.
