| 摘 要： | 对复垦20余年的荔浦锰矿区进行野外调查、采样并对样品进行了室内分析．该矿区共有高等植物22科36种．矿区土壤和13种优势植物内重金属质量分数分析表明，土壤可能已受Mn污染，局部区域受到Cd污染，但Cu，Pb量较低．矿区植物的Cu，Pb量正常，但部分植物的Cd，Mn量超出正常范围．板栗、商陆对Cd和Mn的生物累积系数和生物转移系数均大于1，表现出很强的富集能力，适用于锰矿区废弃地的生态恢复．但作为此矿区主要经济作物的板栗，其果实重金属的质量分数超过中国食品卫生标准，不宜食用． |

| Abstract: | An extensive field survey and sampling were made in 2004 to the Lipu Manganese Mine land which has been reclaimed for over 20 years. 36 plant species from 22 families were recorded in the mineland. Results indicate the soil was probably contaminated by Mn and some regional soils by Cd with Cu and Pb in lower levels. Concentrations of Cu and Pb in plants were in normal range,but for tissues of some plants,Cd and Mn contents were higher than normal range. Both Biological Accumulating Coefficient and Biological Transfer Coefficient were larger than 1 for Castanea henryi and Phytolacca acinosa, indicating these two species are good for the ecological restoration of manganese mine wasteland. As a major economic crop of this restored area ,Chinese chestnut contained heavy metals higher than the allowable safety standards ,thus is not edible for human being. |
