摘  要:
选择伊犁河谷山地草甸群落割草地3个实验区进行采样研究。实验区群落样方由59个常见种组成,属于禾草类、豆科类和杂类草类3个功能群。样方尺度,各功能群的多度、高度、盖度和生物量等均处于性年际变化中,同一功能群内各功能性状间年际变化统计显著性存在差异;区域尺度,各功能群间盖度和生物量年际变化存在统计显著性差异。实验区禾草类相对高度、相对盖度和相对生物量均显著(P<0.01)大于杂类草相应值,杂类草相对盖度和相对生物量以大于豆科类各相应值。伊犁河谷冬季放牧夏季刈割的山地草甸群落形成禾草类—杂类草—豆科类的群落结构类型。

摘  要:
The research selects three experimental areas in Yili valley hay-cutting sub-alpine meadow communities which consist of 59 common species and belong to three functional communities,such as grasses,legumes and forbs.The quadrate scale,the abundances,heights,covers and biomasses vary annually with different significant levels,the annual variances within the same functional groups change statistically significantly; the regional scale,the covers and biomasses of the functional groups change statistically significantly.The relative heights,the relative covers,the relative biomasses of the grasses are significantly(P<0.01) higher than those of the forbs and legumes,the relative covers and the relative biomasses of the forbs are higher than thoses of the legumes with different statistical significances.Yili valley hay-cutting sub-alpine meadow communities constitute the community structures,namely,grasses-forbs-legumes type.
