- Joseph stood by his master s chair telling some tale concerning a lame horse ; and hareton was preparing for the hay field . hallo , nelly
约瑟夫站在他主人的椅子旁边，正在讲着关于一匹跛马的事哈里顿正预备到干草地里去。 - The results indicated that as the intensity of sward cleavage increased , elymus nutans and other plants that had high requirements in soil aeration and resource space presented an increased competitive edge and the species that had low requirements in soil aeration and resource space presented an opposite picture ; low - intensity sward cleavage could help increase species diversity to a certain extent , but the diversity index appeared to decline as a whole as the cleavage intensity increased ; the effects of sward cleavage on functional groups of the vegetations showed in such manner as e . nutans - represented grasses increased in their composition with the intensity of sward cleavage raised , and sedges and forbs decreased in their compositions with the intensity of sward cleavage raised ; sward cleavage showed a significant improving effect on primary productivity of the meadows and was capable of increasing the proportion of quality - grass biomass to the total plant biomass ; sward cleavage could be independently employed as an effective measure to rehabilitate and improve alpine - meadow grasslands and thus played a basic and key role in the technical combination aiming at establishing hay fields characterized by e . nutans
结果表明：垂穗披碱草等对土壤通透性和资源空间要求较高的物种，竞争力随划破强度的增加而上升，而对土壤通透性和资源空间要求相对较低的物种则相反；轻度划破干扰对提高物种丰富度具有一定的促进作用，但多样性指数则总体上表现为随划破强度的增加而呈下降的趋势；划破干扰对植被功能群的影响表现为以垂穗披碱草为代表的禾草类组分随干扰强度的增加而显著上升，莎草类和杂类草组分随干扰强度的增加而显著下降；划破干扰对草地初级生产力的提升具有显著的促进作用，且可显著增加植物总量中优质牧草的比重；划破干扰可独立作为高寒草甸类草地恢复与改良的有效措施，在定向培育垂穗披碱草型割草场的技术组合中具有核心和基础性的地位。
