| 摘 要： | 对临夏县天然草地现状分析表明：由于长期超载过牧，砍、挖、垦荒和干旱少雨，造成了已退化天然草地占可利用草地的75％。建立人工草地，退耕还林还草，以草定畜，划区轮牧和草场承包，是实现该地区天然草地合理持续利用的有效途径。

| Abstract: | Analysis of Linxia County's current natural grassland status indicates that due to long-term overgrazing, chopping, digging, reclaiming wasteland, and aridity with little rain, degraded natural grassland already takes up 75% of utilizable grassland. Establishing cultivated grassland, retiring cultivated land to forest and grassland, setting stock numbers according to forage availability, setting areas and rotational grazing, and having grassland contracts, are the effective ways to realize reasonable sustainable utilization of natural grassland in this area. |
