| 摘 要： | 对矸石土样及植被材料进行采样测定,研究分析矸石的供肥能力、微量有毒元素含量、矿区植物中微量有毒元素的含量。研究结果表明:刺槐(Robinia pseudoacacia)对Cu、As元素吸收能力大于其它植物;荠菜(Capsella bursapastrois)对Zn元素的吸收能力较其他植物强;狗尾草(Setaria viridis)对Cr元素具有较强的吸收能力。依据矸石废弃地立地类型特点,矸石废弃地人工植被景观恢复过程中应选择臭椿(Ailanthus altissima)、刺槐(Robinia pseudoacacia)作为先锋树种,宜优先选用刺槐×沙棘×荠菜(Robinia pseudoacacia×Hippophae rhamnoides×Capsella)、刺槐×沙棘×狗尾草(Robinia pseudoacacia×Hippophae rhamnoides×Setariaviridis)、臭椿×沙棘×狗尾草(Ailanthusaltissima×Hippophae rhamnoides×Setaria viridis)群落与刺槐林、臭椿林配植模式。运用生态恢复的方法对矸石废弃地进行人工植被景观恢复与重建,恢复其受损伤的生态系统,这对矸石废弃地植被恢复有一定的理论指导意义。

| Abstract: | Gangue soil and the vegetation material were carried on the sampling and determination separately.Ability of gangue nutrient supply,the micro virulent element content in the gangue as well as in plants was researched.Result indicated that,Black Locust(Robinia pseudoacacia)shows stronger absorption of Cu, As than other plants.Shepherd's-purse(Capsella bursapastrois)has the strong absorbancy to Zn and Green Bristlegrass Herb(Setaria viridis)to Cr.According to the site type division result,Ailanthus(Ailanthus ... |
