| 摘 要： | 金露梅 (Dasiphorafruticosa)灌丛是祁连山东段牦牛主要的放牧地类型之一。 1月份灌木的现存量为 4 4 4g/m2 DM。齐地面砍伐后生长季末 9月的再生量仅为 2 6 .1g/m2 DM。在冬春 6个模拟放牧梯度试验的基础上 ,获得冬春最适利用率为 11.6 %～ 13.4 % ,最大不退化利用率为 2 8.6 %～ 30 .4 %。

| Abstract: | Dasiphora fruticosa shrubland is one of the major grazing lands for yaks in the eastern Qilian Mountains. The standing crop of shrubland is 444 g/m 2 DM in January. And the regrowth yield of shrubs after 0 cm stubble cut in September is 26.1 g/m 2DM. The results from simulated experiments of 6 grazing intensity show that the optimum utilization rate is 11.6%～13.4%. When the utilization rate reaches 28.6%～ 30.4% , the aftermath of the shrubs is 0. |
