| 摘 要： | 在河北张家口坝上羊苹草原上，选择植被均匀、微地形差异较小的割草地和放牧地作为研究样地，通过对羊草种群的营养枝和根茎两个指标研究表明：割草地与放牧营养枝和根茎呈不显著拮抗关系，放牧地根茎随季节波动性要显著大于割草地。综合分析结果表明，割草地羊草种群的营养枝和根茎生物性状要优于放牧地。 |

| Abstract: | The effects of grazing and cutting on growth of vegetative shoots and rhizomes of Leymus chinensis were studied by selecting the sampling fields with uniform vegetation and less difference of micro-topography in L.chinensis grassland of Bashang plateau,Zhangjiakou in Hebei province.The resulta show that there were no trade-off between the biomass of vegetative shoots and the biomass of rhizome in both grazing fields and mowing fields.The fluctuation of rhizome biomass with the changing of seasons in grazing fields was more significant than that in mowing fields.The results also show that the biological characters of the vegetative shoots and rhizomes of leymus chinensis population in mowing fields were better than those in grazing fields. |
| Keywords: | grassland in Bashang plateau Leymus chinensis vegetative shoot rhizome |
