尾矿库无覆土植被恢复适生植物筛选试验研究

Screening tests of survivable plants in dry tailings pond without covered soil

尾矿库不仅占用了大片土地,而且严重破坏了矿区的生态环境。为了改善矿区生态环境,实现矿山的绿色开采,以迁安永盛工贸有限公司的尾矿库为例,在对铁尾矿进行理化性质分析的基础上,采用尾矿库上无覆土直接种植的方式进行植物的种植试验。田间试验结果表明:杨柴、沙枣、白柠条、赤峰杨等适应尾矿库的立地条件,筛选其为尾矿库生态重建的先锋植物。

The tailings pond not only occupied large tracts of land,but also seriously damaged the ecological environment of mining areas.In order to improve the ecological environment of mining area and achieve green mining as soon as possible,taking Yongsheng Industry and Trade Corporation for example,on the basis of the analysis of physical and chemical properties of iron mine dry tailings pond,several kinds of plants were planted in the tailings pond without covered soil.The results showed that Yangchai,oleaster,White Caragana,and Chifeng Poplar could grow in such conditions.Thus these plants were selected as the pioneer plants of ecological reconstruction of tailings pond.
