| 摘 要： | 采用定位样方调查法和牧草收割法对五台山蓝花棘豆-苔草草甸和白羊草草丛的群落学特征、生物量和优势种的株高动态进行了研究,结果表明,2个群落的物种组成和群落结构表现出明显差异,群落的总生物量分别为7282.98和4184.68g/m2,其中地上部分(茎、叶、花)生物量分别为1018.34和890.08g/m2,地下部分(细根、中根、粗根)生物量分别为6264.64和3294.6g/m2。此外,对2个群落的优势种蓝花棘豆、苔草、白羊草和黄背草从返青期到开花期的株高动态采用Logistic拟合,经F检验均达到极显著性水平,而在成熟期和枯萎期,蓝花棘豆和苔草的株高由于种子脱落或顶端茎秆干枯折断而迅速降低,不符合Logistic增长模型。

| Abstract: | A locating quadrat investigation and forage harvest methods were applied to study the phytocoenological characteristics,biomass and height dynamics in meadows dominated by Oxytropis coerulea and Carex dispalata,or by hassocks of Bothriochloa ischaemum in the Wutai mountains of Shanxi province.Both species composition and community structure differed greatly between the two communities.The total biomasses of the two communities were 7 282.98 and 4 184.68 g/m2 respectively,of which the aboveground biomass (st... |
