摘  要：
对呼伦贝尔草甸草原划区轮牧和自由放牧两种放牧制度植物群落特征进行了比较研究。结果表明:羊草的密度在自由放牧区显著高于划区轮牧区,高度、盖度不同放牧处理之间差异不明显;贝加尔针茅高度和盖度轮牧区显著高于自由放牧区,密度对照区显著高于两放牧处理区;苔草高度、盖度和密度自由放牧区高于划区轮牧区。Margalef丰富度指数、Shannon-wiener指数和Simpson指数划区轮牧区均高于自由放牧区,Pielou指数两放牧区无显著差异,对照区群落的均匀度指数高于放牧区。牧草总的地上现存量8、9月份轮牧区显著高于自由区和对照区。粗蛋白质的含量划区轮牧区显著高于自由放牧区;粗纤维、粗脂肪、钙和无氮浸出物自由放牧区高于划区轮牧区。

摘  要：
Effects of rotational and continuous grazing on plant community characteristics in Hulunbeier meadow steppe were investigated.The results indicated that the density of Leymus chinensis in continuous grazing area was significantly higher than that in rotational grazing area,whereas the height and coverage were not significantly different between the different grazing systems;the height and coverage of Stipa baicalensis in rotational grazing area were significantly higher than that in continuous grazing area,the density of control area was significantly higher than the two grazing treatment area;the height,coverage and density of Carex in continuous grazing area were higher than those in rotational grazing area;Margalef richness index,Shannon-wiener index and Simpson index of rotational grazing area were higher than continuous grazing area,Pielou index of two treatments were not significantly different,and the evenness index of control area was higher than continuous grazing area.The total standing crop of rotational grazing area in August and September were significantly higher than the continuous grazing area and control area.Crude protein content in rotational grazing area was significantly higher than continuous grazing area;contents of crude fiber,crude fat,calcium and nitrogen free extract were higher than rotational grazing area.
