| 摘 要： | 在广西大厂矿区废弃的锡矿尾砂库上进行植被的重建试验。设对照组、垃圾肥处理组和覆土组,种植固氮植物银合欢(Leucaenaleucocephala)。100d时采样分析,垃圾肥处理组的银合欢生长状况最好,重金属从土壤到植物的迁移明显降低,说明在锡矿尾砂库植被重建中,可以利用垃圾肥替代土壤,银合欢可以作为锡矿尾砂库植被重建的先锋树种。 |
| 关 键 词： | 银合欢 城市垃圾肥 锡矿尾砂库 植被重建 |

| Abstract: | Dachang Mining is a famous tin production base of China.Nowadays,most of the abandoned mine tailings dumping grounds are uncovered,resulting in serious regional environmental problems.A field revegetation experiment,composed of 3 treatments,CK,adding in garbage compost,and covering with soil,was carried out on an abandoned tin mine tailing dumping ground at Dachang Mining.The tailings were first amended with garbage compost and soil,and then Leucaena leucocephala trees were planted.In the first 100 days,L.leucocephala on the tailings amended with garbage compost were found growing best.The results showed that the garbage compost significantly decreased plant uptake of heavy metals from the soil,indicating that in the process of vegetation restoration on tin mine tailings dumping grounds,garbage compost can substitute soil,and L.leucocephala can be planted as the pioneer species. |
