中文摘要	对伊犁绢蒿Seriphidium transillense荒漠受损草地植物群落春季数量特征、组分进行测定与分析.结果表明,在放牧胁迫下,植物群落组分由未退化阶段的伊犁绢蒿、叉毛蓬Petrosimonia sibirica、角果藜Ceratocarpus arenarius,转变为极度退化阶段的叉毛蓬、弯果胡芦巴Trigonella arcuata、串珠老鹳草Geranillm transversale;随着草地受损程度的增加,群落的植物种数、密度呈上升趋势;高度呈递减趋势;群落盖度从未退化至中度退化阶段呈下降趋势,中度至极度阶段呈上升趋势;地上生物量具有一定的波动性,但与未退化阶段相比较,其值明显下降;群落经历量变、量变与质变交互、质变的演替过程.
英文摘要	The quantity character and composition of degraded Seriphidium transillense desert rangeland were measured and analyzed. The result showed that the composition of plant community changed from S. transillense, Petrosimonia sibirica, Ceratocarpus arenarius at non-degraded stage to P. sibirica, Trigonella arcuata ,Geranium transwersale at severe degraded stage under grazing stress. With the increasing of the damaged degree, the number of plant species and density of the community increased and plant height decreased accordingly. The coverage decreased from non-degraded stage to medium degradation, but increased from medium degradation to severe degradation. The aboveground biomass fluctuated, but its value decreased apparently compared with non-degradation stage. The plant community has suffered the succession process of quantitative change, quantitative and qualitative mutual change and qualitative change.
