摘要:: 以青海玉树地区主要灌丛鲜卑花群系、百里香杜鹃群系、细枝绣线菊群系和山生柳群系为研究对象，采用样方收获法研究其地上生物量分配特征。结果表明：5种类型的灌丛地上生物量在21.6 ~34.33 t/hm2 之间，地上生物量最大的是细枝绣线菊群系，最小的是金露梅群系，5种灌丛群落地上生物量平均是29.64 t/hm2，不同层次生物量大小顺序是：灌木层＞草本层＞凋落物层，各自生物量占地上生物量的比例分别是73.35%、14.27%、12.35%。5种灌丛类型建群种生物量大小依次是：细枝绣线菊群系＞金露梅群系＞百里香杜鹃群系＞鲜卑花群系＞山生柳群系。影响玉树地区灌丛地上生物量的主要因素是海拔、群落盖度、灌丛高度及放牧。灌丛地上生物量随着海拔的上升而下降，随着群落盖度和灌木高度的增加而增加。放牧对灌木地上生物量的影响机制尚不明确。

Abstract:: n this paper,we study the main shrub types：Sibiraea laevigata(Linn.) Maxim.shrub;Rhododendron thymifolium Maxim.shrub; Spiraea myrtilloides Rehd.shrub; Potentilla fruticosa Linn.shrub; Salix oritrepha Schneid.shrub as the research objects, in the Yushu city, Qinghai province,China. We use the sample harvest method study and analysis the five shrubs aboveground biomass and its allocation patterns. Our results show that: the 5 types of shrub aboveground biomass fluctuated between 21.61~34.33 t/hm2, the largest aboveground biomass is Spiraea myrtilloides Rehd.shrub Potentilla fruticosa Linn.shrub, and the smallest is Potentilla fruticosa Linn.shrub,the average biomass is 29.64 t/hm2. Different levels of the aboveground biomass order is:shrub layers>herb layers>litter layers, the proportions is 73.35%、14.27%、12.35%,respectively. The dominant species aboveground biomass are arranged in order is that: Spiraea 1myrtilloides Rehd.,Potentilla fruticosa Linn.> Rhododendron thymifolium Maxim> Sibiraea laevigata(Linn.) Maxim.> Salix oritrepha Schneid. The shrub aboveground biomass of decline with the rise the altitude, and increase with the community coverage and shrub height. Grazing on shrub aboveground biomass mechanism is not clear.
