摘 要：
以废弃铅锌矿矿渣为同一基质,选择苗期光皮桦(Betula luminifera H.Winkl)、醉鱼草(Buddleja lindleyana Fort.)、芦竹Arundo donax Linn.)及五节芒〔Miscanthus floridulus(Lab.)Warb.ex Schum et Laut〕进行露天盆栽试验,并以生长200d后的4种植物根系及矿渣为研究对象,分析比较了4种植物的根系特征及其对矿渣紧实度、抗冲抗蚀性的影响。结果显示,4种植物的地下生物量大小为芦竹>醉鱼草>五节芒>苗期光皮桦,并且芦竹的根系总量明显大于其他3种植物;4种植物对矿渣的抗蚀性和抗冲性均有明显增强效应,芦竹对矿渣抗冲抗蚀性的增强效果最明显,其中芦竹对矿渣抗蚀增强系数达0.98,对矿渣抗冲性增强值为26.63。矿渣受侵蚀减缓率与植物根系生物量成显著正相关关系。

摘 要：
On the same lead/zinc mine slag,the four plants of seedling stage light birch,buddleia,bamboo reed and Miscanthus floridulus were selected for an outdoor pot experiment.By taking the four plants roots after 200days growth and slag as the research object,root system features and their effects on slag antiscourability,anti-erodibility and compatibility were studied.Results showed that the underground biomasses of the four plants were in the order of bamboo reed> buddleia> Miscanthus floridulus > seedling stage light birch.Root volume of bamboo reed was significantly greater than other three plants.The four plants had obvious enhancement effect on slag anti-scourability and anti-erodibility.Bamboo reed showed the most significant effect,with the enhancement coefficient of 0.98for slag anti-erodibility and the enhancement value of 26.63for slag anti-scourability.A significant positive correlation was found for the relationship between the root biomass of the plants and the decreased rate of slag erosion.
