Different soil compositions were tested by observing the growth of arbuscular mycorrhizal （AM） fungi inoculated white clover, rye grass or com. The biomass of the host plants, the mycorrhizal colonization （MC） rate and the mycorrhizal depen- dency （MD） were measured. The research addresses the preferable AMF-plant-substrate combination appropriate for restoration of coal mines. We used two inoculation methods： single-inoculation with Glomus versiforme or Glomus mosseae and a dual inocula- tion with both Ctv and Gm. The results show that G^m is the preferable fungi and that dual inoculation does not show advantages for the restoration of coal mines. White clover inoculated with AM fungi is the most suitable condition for restoration of coal mines. The best weight ratio of fly ash, coal gangue and excess sludge was found to be 20：60：20. The optimum treatment conditions of AMF-plant-activated-substrate are described.展开更多

The results indicate that minimum error occurred when distribution curves were transformed by keeping imperfection I constant. Generalized distribution curves are developed for jigs and their applications are discussed.展开更多
