  4. Plant endemism is the key problem in floristic study. analysis of endemism in a flora has significant implications in demonstrating floristic richness and diversity, the relationship between plants and their environment, and also in conserving biodiversity of the flora. in view of the situation that most of the past studies on endemism were qualitative, this study is the first tentative approach to the introduction of quantitative indices to the analysis of floristic endemism, with an purpose to push the study of endemism from qualitative to quantitative. four quantitative indices are introduced, i. e. level of endemism ( l ), coefficient of endemism ( c ), degree of endemism ( d ) and general index of endemism ( a ). mathematical formulae have been given to each of the above indices and explanations for them have been presented, and the scope of their use in floristic studies has been delimited and exemplified in this paper. the result shows that they are of good applicability. the proposed indices embody full information of plant systematics and plant geography. with the aid of qualitative analysis, the application of the proposed indices will improve the comparability and precision of endemism study in floristics

    過去有關特有現象的研究主要限於定性的分析,可比性和精確性較差.該文嘗試引入特有現象的定量化標,以推動特有現象的分析研究從定性水平定量水平邁進.所引入的4種定量化標分別是:特有水平、特有系數、特有度以及特有綜合數.對每種量化標都給出了數學表達式,說明了其區系學意義,例證和界定了這些標在區系分析中的應用,結果表明,它們有良好的適用性.這些標充分地包含了系統學和區系學的信息.結合定性分析,這些標的應用將增強區系研究的可比性,使區系特有現象的分析達到更精確的水平

  7. 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種則相反;輕度劃破干擾對提高種豐富度具有一定的促進作用,但多樣性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。
