| 摘 要： | 不同放牧制度干扰对半固定沙地主要植物达乌里胡枝子和白草现存量无影响,轮牧区达乌里胡枝子高度和虫实、山窝苣、赖草和冰草等密度和盖度显著高于自由放牧区.轮牧区多年生草本植物和一年生草本植物地上现存量高于自由放牧区,一年生植物地上现存量显著高于多年生植物地上现存量.两个放牧处理群落总密度、总盖度无显著差异.

| Abstract: | The results showed that no significant differences in the standing crops of Lespedeza davurica and Pennisetum centrasiaticum were found between the rotational grazing area and continuous grazing area; however, it was found that the relative height of Lespedeza davurica, the relative coverage and density of Lactuca indica, Leymus secalinus and Agrostis cristatum were significantly higher in the rotational grazing area than the one＇s in the continuous grazing area. The standing above-ground biomass of perennial herbs and annual herbs in the rotational grazing area was significantly higher than the one＇s in the continuous grazing area; also, the standing above-ground biomass of annual herbs was significantly higher than the perennial herbs＇ in the same grazing area. The analysis indicated that the community coverage and density between the two grazing areas were not significantly different. |
