摘　　要：选择祁连山自然保护区4处典型砂石料场植被恢复地为研究对象,研究其植被恢复技术和林下草本植被的物种多样性。结果表明:砂石料场植被恢复技术主要是采坑回填、废弃渣堆平整、河道清淤、废弃建筑物拆除、排导堤修筑、围栏封育、覆土、种植单一的乔木或灌木以及草本植物种。林下植物以冷地早熟禾(Poa crymophila)和垂穗披碱草(Elymus nutans)占据优势地位,其他植物种处于劣势地位。林下植被Margalef物种丰富度指数、Simpson多样性指数、Shannon-Wiener多样性指数和Pielous均匀度指数均偏小,植物多样性维持在较低水平。建议继续加强祁连山自然保护区砂石料场植被恢复区的经营和管理。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 vegetation.The results showed as follows:the vegetation restoration technology in sandstone material yard mainly included 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 disadvantage;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.
