摘要
通过开放式的定点样方笼移动法,监测当前放牧强度下草地的产草量与不同阶段的存量,以此估算夏草地的合理放牧强度。监测结果显示:裕民县禾草+苔草+杂类草类型夏草地的牧草产量为鲜草5 238kg/hm2,干草2 017kg/hm2实际利用率约为84%,超载率约40%,合理放牧强度为9.96羊单位/hm2,放牧90d。
The paper reported the stocking rate with monitoring the forage yield before and after grazing. The results reveled that the fresh forage yield and dry matter yield of rangeland with grass,carex and forbs were 5 238 kg/hm^2 and 2 017 kg/hm^2 ,respectively. The actual rangeland utilization rate was 84%,and the overstocking rate was 40%,the carrying capacity was 9.96 (Sheep Unit) per hectare for 90 days.
