摘  要:
以大针茅+羊草草地为研究对象,设置割草场和放牧场两种利用方式样地,并分别对其主要植物种及群落功能群的地上生物量、高度、盖度、密度的变化进行研究。结果表明:糙隐子草在放牧场的地上生物量与密度显著高于割草场,而麻花头在割草场的地上生物量显著高于放牧场(P<0.05);羊草和麻花头在割草场的高度显著高于放牧场(P<0.05);主要植物种的盖度在两种利用方式下均无显著性差异(P>0.05)。除多年生禾草以外,多年生杂类草、一、二年生草本与小半灌木在不同利用方式下均差异显著(P<0.05)。总体来说,放牧对群落主要植物种的影响很明显。

摘  要:
Taking the grassland of Stipa grandis + Leymus chinensis as research object,the research on the change of above- ground biomass,height,coverage and density of main plant species and functional group have been done in mowing pasture and grazing pasture. The results show that the above- ground biomass and density of Cleistogenes squarrosa in grazing pasture are higher than the ones in mowing pasture obviously,the above- ground biomass of Serratula centauroides in mowing pasture is higher than the one in grazing pasture obviously( P < 0. 05),and the height of Leymus chinensis and Serratula centauroides in mowing pasture are higher than the ones in grazing pasture obviously( P < 0. 05). There isn't significant difference for the coverage of main plant species with two kinds of utilization patterns( P > 0. 05). Except perennial grass,there is significant difference for perennial weeds,1 ~ 2-year herbs and semishrub with different utilization patterns( P < 0. 05). In general,grazing can obviously influence the main plant species of community.
