  4. 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

    結果表明：垂穗披堿草等對土壤通透性和資源空間要求較高的物種，競爭力隨劃破強度的增加而上升，而對土壤通透性和資源空間要求相對較低的物種則相反；輕度劃破干擾對提高物種豐富度具有一定的促進作用，但多樣性指數則總體上表現為隨劃破強度的增加而呈下降的趨勢；劃破干擾對植被功能群的影響表現為以垂穗披堿草為代表的禾草類組分隨干擾強度的增加而顯著上升，莎草類和雜類草組分隨干擾強度的增加而顯著下降；劃破干擾對草地初級生產力的提升具有顯著的促進作用，且可顯著增加植物總量中優質牧草的比重；劃破干擾可獨立作為高寒草甸類草地恢復與改良的有效措施，在定向培育垂穗披堿草型割草場的技術組合中具有核心和基礎性的地位。
