| 摘 要： | 本文研究了短花针茅荒漠草原划区轮牧和自由放牧两种放牧制度群落及主要植物种群特征变化,结果表明:经过3年的轮牧试验后,划区轮牧区群落及主要植物种群的高度、盖度、密度均较自由放牧区有不同程度的提高。划区轮牧区与自由放牧区相比,草地基况有明显好转,而自由放牧区一些退化植物、一年生植物、杂类草在草群中的高度、盖度、密度有所增加。划区轮牧区现存量高于自由放牧区。

| Abstract: | The characteristics of community and main plant species were studied under rotational grazing and continuousgrazing in desert steppe ofStipa breviflore.The results showed that the height,coverage,and density of the population and the main plant species under rotational grazing were higher than that under continuous grazing during the period of the experiment in three years.The range conditionimproved apparently under rotational grazing,however,the height,coverage,and density of degenerative plants,annual plants and weeds were increased under continuous grazing.The standing crops in the fields under rotational grazing were higher than that under continuous grazing. |
