The results show that the construction of the railway has an obvious effect on the warm steppe,but the characteristics of community,such as the coverage,ecological dominance and species richness of communities have been improved after its natural restoration,and some species,such as Elymus nutans,Aconitum gymnandrum and Thermopsis lanceolata,play an important role in the restoration communities.An assistant measure taken by human beings will benefit to the restoration.There is no any evidence of exotic invading plants in the restoration of the warm steppe in the study area.

结果显示，青藏铁路修筑过程对铁路两侧一定区域的温性草原有较大影响，但随着受影响区域植被的自然恢复，群落盖度、生态优势度和物种多样性等反应群落特征的指标都有一定程度的改善，一些在原生植被中很少出现或伴生种在恢复后的群落中有可能成为群落的优势种或建群种，如露蕊乌头和鹅绒委陵菜等；人为辅助措施将有利于受损植被的恢复；修筑铁路过程中受到影响的温性草原其恢复过程中尚未出现外来入侵植物。

垂穗披碱草和冷地早熟禾地上、地下生物量沿海拔高度的升高而降低，且前者生物量大于后者；两者的植株高度和根系长度随海拔不同而不同，都在3400m处最大，前者大于后者。

There were significant differences in tiller ability among lines of BC1F2 and BC1F3,some lines had strong tiller ability that correspond to parent H. brevisubulatum, and some lines had lower tiller ability that were inferior to parent Elymus dahuricus.

BC1F2、BC1F3代各株系的分蘖能力有较大变异，有的株系分蘖能力很强，与亲本野大麦相当，有的则很弱，不及披碱草。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
