摘要
The population density,caloric value and energy accumulation of Dactylis.glomeratawere significantly increased after moderate grazing.Tuft size was decreased,while the tuft density was significantly increased due to the high grazing intensity which showed the different reproductive strategies on the sites with various grazing intensities.Both inadequate grazing and over-grazing lowered the density and energy accumulation of D.glomerata.65% rate of consumption of the grasses,or 4 times of mowing in 1 year contributed to the rapid growth of D.glomerata and the sustainable development of the grassland.
