In field investigations, mycorrhizal fungal communities in different mine tailings and heavy-metal contaminated soils in the central south China and effects of mycorrhizal fungal infection on hose-tree growth on the tailings were investigated. As a result, a phylogenetically diverse communities associated with Masson pine and different structures of mycorrhizal fungal communities among different mine sites were found. In laboratory investigations, the heavy-metal tolerances(Cu, Zn, Pb, Ni, Cd) of 50 ectomycorrhizal fungal species were screened and some species which would be available for revegetation in mine tailings and heavy-metal contaminated soils were detected. Furthermore, response mechanisms of ectomycorrhizal fungus-host trees to different heavy-metal stresses were also investigated.

通过野外调查，研究了中南地区不同尾矿库和重金属污染土壤中的菌根真菌群落，以及菌根真菌感染对尾矿库水龙树生长的影响。通过室内调查，筛选出50种外生菌根真菌对Cu、Zn、Pb、Ni、Cd等重金属的耐受性，并筛选出部分可用于矿山尾矿和重金属污染土壤植被恢复的外生菌根真菌。此外，还研究了外生菌根菌寄主树木对不同重金属胁迫的响应机制。
