| 摘 要： | 通过研究青海环湖区高寒草甸草场刈割及放牧对牧草的补偿性生长效应，发现轻度刈割和中度刈割后牧草为超补偿生长，重度刈割后为欠补偿生长；轻度放牧条件下可显著提高牧草总产量，中度放牧条件下基本能保持牧草总产量。

| Abstract: | Recovering effect of cradle and grazing on growth of forage was researched in grassland of Qinghai lake area. The results indicated that the forage was over - compensating growth after being cradled lightly or middlingly, but it was under- compensating growth after being cradled heavily. The forage yield increased significantly under the condition of hght grazing, it didnit change obviously under the condition of middle grazing. |
