| 摘 要： | 在内蒙古锡林郭勒盟苏尼特右旗荒漠草原,通过划区轮牧与自由放牧的比较试验,研究了不同放牧制度对短花针茅荒漠草原优势种群的影响,结果表明:自由放牧区短花针茅高度、盖度、密度、重要值、相对现存量均高于划区轮牧区。划区轮牧区无芒隐子草和碱韭的盖度、密度、重要值、地上现存量和相对现存量均高于自由放牧区。

| Abstract: | The comparative study on the dominant species population under the two different grazing systems in Stipa breviflora Steppe were conducted.The results showed that the height,the density, the coverage,the importance value,and the relative standing crop of Stipa breviflora in continuous grazing were higher than that in rotational grazing.However,the coverage,the density,the importance value,the above ground standing crop and the relative standing crop of Cleistogenes songorica and Allium polyhizum in rotational grazing were higher than that in continuous grazing. |
