摘　　要：本试验于2010年在本氏针茅温性草原进行不同载畜率植物净生长量的比较研究,主要探讨黄土高原丘陵沟壑区本氏针茅草原不同载畜率对植物补偿性生长的影响。研究结果表明:CK、A、B、C、D区群落地上生物量显著高于E、F区(P<0.05),表现为欠补偿性生长;主要植物种群的净生长量在不同放牧处理间存在差异,从而表现不同的补偿性生长趋势。The trial was comparison research in the krylovii warm Steppe under different stocking rates on plant net growth in 2010,mainly the effect of krylovii grassland under different stocking rates on plant compensatory growth in the hilly area of the Loess Plateau.The results showed that：CK,A,B,C,D ground biomass of the community was significantly higher than that of E,F（P 0.05）,which showed less compensatory growth.The net growth of main plant populations in different grazing were to deal with difference,which showed different compensatory growth trend.

关 键 词：本氏针茅温性草原 载畜率 补偿性生长 净生长量
