Four typical vegetation restoration sites in the sandstone material yard of Qilian Mountain Nature Reserve were selected to study the vegetation restoration technology and the species diversity of understory herbaceous vege-tation.The results showed as follows:the vegetation restoration technology in sandstone material yard mainly in-cluded pit backfilling,waste slag heap leveling,river dredging,abandoned building demolition,drainage embankment construction,fence enclosure,soil covering,planting single tree or shrub and herbaceous plant species;among the understory plants,Poa crymophila and Elymus nutans were dominant,while other plant species were at a disadvan-tage;the Margalef species richness index,Simpson diversity index,Shannon-Wiener diversity index and Pielous evenness index of understory vegetation were all small,and the plant diversity was maintained at a low level.It is suggested to continue to strengthen the operation and management of the vegetation restoration area of the sandstone material yard in Qilian Mountain Nature Reserve.
