| 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、S... |

| Abstract: | 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,... |
